John,I have also to admit to having being "caught" ,just the once, in a workshop restoring 1920's Sunbeams, I was doing the wooden body framing ,and Willy, the son, asked me to go into the machine shop to get the "struggle weight" which turned out to be a great chunk of 4" steel bar, that must have weighed 100lb's or more! and on returning I was greeted by raucous laughter...mmmm!, by the way, these guys are incredible!, I still see them often, they also make 3 litre sunbeam engines with superchargers from scratch!, obviously with castings that they get made, but the workshop is the biggest mess you've ever seen!, I must remember to take some pics when I go back to the UK ,and post them ,it's quite something!, there could even be some long dead machinist lying behind a lathe somewhere!...Giles
