I just recently looked through an "accumulation" of insulators from a gentleman who was moving to Florida. A couple of better pieces in the bunch, but the majority were common railroad insulators. He said that they were collected by his father. In his possession was this sales list, that I would guess, dates from the 70's. Any idea who's list this is, and if they're still active in the hobby? I'll bring it along to the National next week. Anyone got a honey amber H.G.Co. for $47.50??
