Ken Solway’s book is likely the most accurate accounting of where the forms went that we now have. Of course now the question is where did the forms he have go to. Carl Jones got some (when Chestnut closed) and started Cedarwood Canoes. I am not sure where he is, though I know of one Cedarwood Canoe Prospector owned by a Norumbega chapter member.
Actually there might not have been that many 16, 17, and 18 foot forms available when Chestnut closed. Solway writes that for the Pleasure model – their most popular canoe – Chestnut needed 3 forms to keep up with demand. That suggests, at the most, two forms for the 16, 17, and 18 prospector models.
Years ago, I saw a catalogue of all canoe and kayaks being built (I think compiled in Canoe & Kayak), and like ALL the Canadian builders, Kevlar and fiberglass, had a complete line of clone Prospectors. So yeah, with all those fellas in the game, you are gonna get some phonies.
