It was our clubs auction night last night, where members donate unwanted item to be auctioned off for club funds. As the action was coming to an end a lot of miscellaneous item came under the item there were all sorts of bits of bobs in it that included sealing wax and a 1/2" micrometre, now 1/2" mics are unusual I have only come across one before that belonged to an old work colleague, he kept it in his draw using it from time to time as the need arose, knowing he had it I also borrowed it, there was something real sweet about it just sat in your hand. Before a could cuck in a bid someone piped up I'll give you £4 quid was the wax, bang sold, so I asked the buyer if he would sell me the mic, no I won't sell it i'll give it you he said and handed it to me, so in the sprit of the occasion I put £1 into the pop.
It was made by a firm called ROBBLAK (never heard of them) it has a previous owners name lightly engraved in it G.Haris. and on the other face its stamped up as FOREIGN No 502 and it has a company calibration reference number etched 4D
When I got it home I stripped down and stuck the parts in my ultrasonic cleaner to get rid of the gunk, I then put it back together zeroed it up checked it across its range with slips it was spot on the locking ring works and the ratchet was nice and sweet. It now sits on my desk where I find myself handing and as a kind of comforter. Its a real nice bit of kit to just hold:- yes I know I'm a sad old bastard but I just love tools
