With WW Greener,the # represented price in Guineas at the time of manufacture , didn't it?,or at least some of them?
(shoot , I nearly wrote Guinness, ha ha), so that might help with his guns.Some of those awesome looking scallop shell fenced boxlocks in the 70 or 75g were lovely looking, surely Best Boxlocks?
There are a couple on FoxHill, & Double Gun HQ sites I believe
Its a tough subject for sure.
Cheers
