Ravensden ROC Post – Bedfordshire Group

Opened – Unknown
Closed – October 1968


There isn’t too much that can be said about this post as you can see from the pictures. I’m not entirely sure when it was capped with concrete and steel bar but its at least 15 years ago, also I’m not sure if it is just a cap or in fact they poured rubble down the shaft and topped it with concrete. If I run out of things to do before I die I might go back with a large can of PlusGas and ‘FSM Cam’ it just out of idle curiosity.

Great location geographically with great vision all round, or certainly would have been before the odd building and trees that have sprang up since the 1950’s. Bedford is one of those unusual counties with very few ROC Posts, despite the fact that Bedford ROC Group HQ No 7 was the HQ for the UKWMO Midlands Sector, covering many more counties at the time.

Nature has certainly claimed back this post…

Plessey Controls PDRM82 Portable Dose Rate Meter/Geiger Counter

Back at the start of the Cold War the first mass produced Civil Defence Geiger Counter was the Geiger-Müller counter Meter, Contamination, No. 1 set – stock number 5CG0012, of 1953. You still see these from time to time and many remained in use into the 1980’s. It was replaced in 1956 by the British Radiac Survey Meter No 2 which was adopted by the Royal Observer Corps until they took delivery of the better known and specifically built Fixed Survey Meter.

In 1982 Plessey Controls introduced the PDRM82 Portable Dose Rate Meter and this became standard issue for both Civil Defence and Military applications, a special version was created for the Royal Observer Corps, the PDRM82(F) which had an external Coax cable allowing connection to an above ground ionisation detector which ran up the FSM Tube to a polycarbonate dome.

Surprisingly these are allegedly still standard Military Issue today, despite significant advances in technology!!

We recently bought a couple on eBay for exploring a site that in the past was known for having ‘radioactive content’ but despite coming across very real evidence of radioactive items, including Cobalt-60 storage, we could not get even the faintest reading anywhere at the site….kind of good really as had the PDRM82 ‘lit up’ we would have been a bit freaked out….

Market Deeping ROC Post – Northamptonshire Group

Opened – March 1960
Closed – September 1991
The last post visited as part of an ‘8 ROC Posts in one day’ tour and probably the mintiest ROC Post i’ve visited to date. Actually I didn’t really want to post this one up as it just serves as temptation for some morons to come and trash it and steal its contents but then I thought if I don’t post it up then someone else will…..its fate is sealed either way I guess…..hopefully someone will put a massive lock on it to protect this for future generations of visitors, who knows.

Some pix suffer from me experimenting with camera settings which I promise not to do while out in the field again…

Castor ROC Post – Northamptonshire Group

Opened – February 1962
Closed – October 1968
Explored as part of an 8 ROC Posts in one day tour we visited Castor ROC Post, location of a well publicised suicide by a local farmer some years ago who hanged himself in the access shaft. Perhaps this has put off the chavs as the post is in no worse condition that when Sub Brit visited back in 1997, apart from the fact that the compound is now totally overgrown and it took us several laps of the site to locate the hatch and crawl on our hands and knees through the undergrowth.

Good deed of the day was rescuing a sick looking toad that probably fell down the severed at ground level FSM tube and bringing it back to the surface.

Also present at this site is a great example of an Aicraft Observation Post, originally this would have had a canvas cover on top and some steps.

I was experimenting with camera settings so apologies for the quality on some shots.

Moulton Chapel ROC Post – Lincolnshire Group

Opened – July 1960
Closed – October 1968
Explored as part of an ‘8 ROC Posts in one day’ tour sadly this was one of several sorry looking posts we came across. ‘Decorated’ my local morons in a fetching yellow and blue colour scheme, some smoke damage to the roof tiles and a shattered sump grate welcoming us below ground. The cupboard had been partially destroyed but there was an intact hand operated siren crate.

The compound was in a fantastic location on the edge of a cornfield and contains the demolished remains of a brick Aircraft Observation Post, also in the compound are several beehives….complete with LOTS of bees….needless to say we chose a swift and different exit on the way out as we had accidentally disturbed them on the way in.

Yet again I was experimenting with camera settings (epic fail on most which got deleted…) so apologies for the quality on some shots.

Wansford ROC Post – Northamptonshire Group

Opened – February 1962
Closed – October 1968
Even more from the ‘8 ROC Posts in one day’ tour. We knew in advance that this one was badly trashed and that was certainly the case but we needed to visit to tick off some remaining Northants Group posts.

As previously stated I was experimenting with camera settings (epic fail on most which got deleted ) so apologies for the lame shots.

Also present at this site was a brick Aircraft Observation Post from an earlier time in ROC history, this would have been linked up to HQ with a land line using a Magneto Telephone.The other unusual item in the pictures is a very old cashbox from a BT pay-on-answer public phone box, quite what that was doing up here I don’t know, unless it was robbed then dragged up here to be prised open…

Upwell ROC Post – Norfolk Group

Opened – October 1959
Closed – September 1991
More from the ‘8 ROC Posts in one day’ tour. Once we caught sight of the telegraph poles disappearing into a field we were well happy as this was a Master Post but sadly on reaching the compound it was a major disappointment as it was seriously locked down (pictures elsewhere show this to be very tidy inside). The exterior was a lovely shade of green though with no obvious damage to anything. Not sure if they built this too low by mistake but the FSM tube has an extension and the hatch is well low in the ground!!

Supposedly this has been bought by someone but I don’t know for sure. Whoever is taking care of it has secured it very well and as we were tight on time we couldn’t really spend time finding out.

A Tube Cam was also out of the question unless we had a monster can of EAC Plus Gas and a spare day…..we had neither 🙁

Parson Drove ROC Post – Cambridgeshire Group (FSM Tube Cam)

Opened – March 1960
Closed – September 1991
Another post visited as part of an ‘8 ROC Posts in one day’ tour, Parson Drove had been ingeniously locked with a cleverly fitted mortice lock so became our first ‘fail’ of the day in respect of underground shots. The post was recently sold on eBay to someone in Oakham, Rutland but it looks like nothing has been done to it apart from the fancy lock.

Never one to be outwitted I broke out the Tube Cam Kit and did some ‘remote photography’. The interior looks to be the same as its always been with the red spray paint noted by Sub Brit back in 1999. My Tube Cam Kit is due to be modified in the future to provide precise shots, these ones are a bit poor but its better than nothing.

The famous Shetland pony is still there, it crept up on us and was attempting to eat Winch It In’s Canon kit while we had our backs turned doing the Tube Cam !!
