Fred,
That was quite an investment in that O grade lifter for $20! You could easily double your money today
As far as Parker information goes, the Parker Pages is also fabulous. When I first joined PGCA in 1995 it was just a few Xerox pages stapled together. I then wandered away into the wilds of Siberia and Antarctica searching for extremophiles and meteorites and lost contact with PGCA. When I re-joined a couple of months ago, I was astonished to see what a beautiful publication it had evolved into.
Thanks are truly due to Austin Hogan, Dean Romig, Larry Frey, and the Associate and Contributing Editors and authors who have put so much work into this fine publication that does justice to these magnificent shotguns.
