The imminent loss of Weaver led me to wonder about other hobby manufacturers that have vanished. I can think of a list:
K-Line, and Williams, of course, but what has happened to Keil Line...did anybody pick that up like they did the mfr. of parts from Mass. (can't think of the name or quickly find a package)? Keil Line made many of the parts that had been included in old Walthers kits, and later All-Nation, and nobody picked up All-Nation (lucky I have several of those old Waltheres kits). There was a shaped wood maker (O scale car roofs, siding, etc.) on the east coast, I think, that got out of the business. Crown, and a Colorado-based plastic car kit maker, others I can't think of......?
