Some years ago I bought this at a market but to date nobody has been able to tell me what it is. It looked well made and just as important it was very CHEAP so I bought it on the basis I would try and find out what it was later - the time has now come...................

I showed it to Roy Arnold at the old tool shop in Suffolk and he said he didn't know what it was but he had one as well so it seems it was not a one off special.

The cranked arm at the front has a point like a screwdriver tip and the whole arm can be lifted against the tension of the spring in the body of the tool. The spring tension is adjustable with the knob on the back and the scale shows 0 to 200 somethings. There is also a locknut on the back to presumably keep the setting.

The cranked arm at the front can be located in any of four positions at 90 degrees to each other.

I have included a photo of what I assume is the maker's mark if that is any clue.

It would be good to know what this is for and I hope that someone might recognise it - of course, if anybody needs one, it is available at a very resonable rental!

Thanks in anticipation - Bob

Hi Bob,
My guess would be some kind of tension guage. Possibly for setting the spring tension on relays.

Hi Bob,

Les J 1 is correct. They were used by the GPO/BT for adjusting the relays. I've got one, maybe two

. Have used it/them to check triggers on rifles. Mine is stamped GEC, paint obscuring the other printing..

Regards, Bear..

Thanks for all the replies. Now I know what it is I am off down the road, under the cover of darkness, to check and adjust the relays on my local BT box. I assume they are still using these with the new fangled "infinity" box which has just appeared - the lock just looks a bit more substantial than on the old box!

Thanks again for the answer - I can now go to bed happier

By the way - if anyone can make use of it - it's yours for the price of a stamp.

Bob
