Oh, caps all round on ZA7 11072. Should be easy enough to get new ones turned from a suitable steel and 'harden end' with oxyacetylene and an oil quench. Used to do that piecework in a valve factory, breakneck pace to get bonus with 1000C shizzel. 'Test end' was worse, faster pace and putting it in the jig wonky would tempt it to shoot out at you. How we laughed. Pics of caps on and off below.
