However, there is a website for Great Spirit Canoes (http://www.greatspiritcanoes.com/html/canoes.htm) in Oromocto, New Brunswick, which appears to be a native canoe venture which claims to build both 16 and 17 foot Prospectors. Informational details on their website are few but an direct inquiry might elicit information on the source of their forms, especially if one were an potential buyer. Good luck and I would be interested if you find out that they do have original Chestnut forms.
Great Spirit Canoes was formed by buying the Cedarwood Canoes business a few years back, so they would have the original Chestnut molds that Carl Jones brought to Cedarwood, plus any molds that Carl and Stephen subsequently built, I suppose.
