Hi Norm, I agree with Ken, there is nothing like an old vet boring story, I`d love to hear them all! I`ve heard many stories from Czechoslovak veterans from Dunkerque from 1944-1945. The minefields were the biggest fright to them when on patrol as the Germans kept rebuilding the minefields every time when cleared.
Back to my very first question, is there someone who can help me with the No.III mine detector top rod dimensions - especially the counterweight please. Thanks Dusan

I used to have a Mine Detector No.III (Polish) when I was a boy. It had no valves in it, I think there should have been three. I took some ARP12 (Army Receiving Pentode No.12) from a 38 set.
Well that needed 3 volts for the heaters which I got from a cycle lamp battery. The HT for a 38 set was 150 volts, but I used to use an Every Ready "Winner" battery which I think gave 60, 90 or 120 volts. So I fitted that as well & it worked a treat even on 120 volts. The large search head was heavy, particularly as to counter balance it there was a large weight at the top end. The small search head was easier but that had a rather short handle even for a boy to carry. This was about 1958. The detector amplifier cost me 12/6 in a scarpyard. The large head 6/6 the smaller head 4/6 from Arthur Sallis surplus, 93 North Road, in Brighton. Trouble was the heads came through the post & they were fitted into a box by sawing through the support arms & cables! I also remember he sold time bomb mechanisms! You could set these between 15 min to 44 days. Small clockwork mechanism ran for about 5 min then as it ran down it made a contact to energise a solenoid to pull the lever back & so winding it up again. Surprising even then that such things were on sale given that the IRA started a campaign from 1956 that lasted until 1962.
