One has to be a PGCA member to access and use the For Sale forum. Access to this forum is worth the cost of membership for Members often list Parkers, other vintage shotguns, and accessories there first. Transactions are usually smooth although some tend to generate a lot discussion
I have sold at least one Parker on the For Sale forum and bought three or was it four?
When one adds to the Members Only Forums the quarterly printed "glossy" Parker Pages with articles by members including me, the $40 sent on membership will seem a small amount indeed!
