Hi John,
many thanks for another entertaining write-up. I particularly enjoyed the comments regarding EF50s.
I remember as a boy being intrigued by these valves in metal jackets. Without wishing to hi-jack this thread I came across a webpage named, if I remember correctly "EF50 the valve that won the war". It makes fascinating reading.
I look forward to reading the next episode of the Peto Scott saga. BTW I'm pleased it is not only my workbench that is "well populated"
Regards
