:?:
Does anyone know roundabout the time when Parker dropped the circled grp. size stampings?
Late 60's?
Early 70's?
Or later?
Maybe after the merger with Hardcastle in '67?
I'm thinking that they added the grp. size stamp after they dropped the patent in 1957?
Would very much appreciate any answers!
