Old guy here that loves sxs's, combo guns and drillings. Plus a dedicated coyote caller.
I bought an English 10ga sxs that seems to date from the 1870/80's. It is an upland gun(28" barrels and 7 lb 14 oz straight grip) I believe and I've been looking for one that I could afford for 57 yrs after my buddy bought one out from under me in college. This sight seems to have the most info on reloading short 10ga ammo.
10ga WW Forsyth along side my 12ga bird gun.
Sorry I'm not a Parker collector but I wouldn't turn down a 10ga Lifter model I could afford.
Thank you for letting me come aboard.
