One of these days I'll take you on a nostalgic memorable journey through a huge Base Workshop Armourers and A-vehicle (tank) shop F-10. H&S was in its infancy in the late 70's or so and the uncovered trichlorethylene vapour tank would swallow a complete Merlin/Meteor engine PLUS my complete MGB GT V8 front crossmember. and rear axle. And the paint bays stretched for 40 yards - including the sunkorite bays that sprayed and baked said crossmember and axle. We didn't need to wash our hands..........we just dipped them in the tricho tank. I suppose our one concession was that we opened the windows. And so far as I know, we're all still here complete with all of our marbles........ It's all about ........ just thinking of the word.........
