Have now had a quick look at some links on the internet and it does look right for the JWW Pompeian.
Also had another good look for a mark, and found one! It definitely has the word England etched with another over it which could well be Walsh. Mary thought I was mad when I said I'd found a mark and spent about 5 minutes trying to find it, which she did eventually!
Is it collectable and/or valuable?
Also, will change the title as suggested!
Very many thanks, John.
PS going to watch the Grand Prix now, so may not be back for an hour or two!
