Thanks Dennis
I did look on the head as a last resort, all to no avail, also checked the usual casting web near the starter & on the LH side of the lower block.
On the lower block, I can see a faint trace of where it originaly was ( I think ) .... Tried the polishing & photograping trick but can't realy make anything out.
Not a bad idea of yours, looking at one in a breakers, I know the number was probably etched with a series of dots.
I guess if I found a suitable font & the correct format, I could print a template & use my automatic centre punch to re etch the number.
Cheers
