Good morning W Martin.
No need to be "sorry" at all - we obviously were typing at the same time - I just hit "Send" before you. Enjoyed your comments about Brit money. I had to learn my LSD during the six weeks of summer 1963 when I was the (18 year old) family escort for my 80 year old grandmother on her last visit back to New Mills, Dunfermline in Fife(?) When I was actually handling the odd Brit coins my "frugal Scot" ethnicity kicked in and learned "LSD" really fast.
I read this thread because of my (only) Greener. It's a FH35, Facile Princeps two barrel cased set. 26" and 32" barrels both showing "20 over LC" within the diamond, both proofed with 2-7/8" shells, English hand, double triggers, serial no. 67,XXX.
Bought it for my wife (LOP 13-5/8") but she much prefers her Remington 1100 Light-20 (SERIOUS Gaaaarrrrgh).
