Gentlemen,
I would like to sing the praises of David Harris, Stat Eng help line, Dan reminded me about him so last Sunday I wrote David a letter regarding my broken valve guide for my Lister M and by almost return of post received a nice letter with possible suppliers of CS guides and drawings of the original valve guide to modify or make originals. I am now looking for some cast iron bar 1.5 in od to make them.
