Not my post but seemed recent enough for your use.... hope it helps sir.
A company called DROLET in Canada now carries Godin stoves. Here is their website: www.drolet.ca/EngIndex2.htm
This is their Godin page: www.drolet.ca/ProBCA/EIndex-Bca.htm
Here is how to get parts: www.drolet.ca/EngOptions.asp?Type=Part
I called the number on that page, 800-363-0566, and the people there were very helpful. This number is for Inventex which is the company that handles the parts sales for Drolet. They had my Godin stove part that I needed and have shipped it.
11/2007 A site search of Drolet did not turn up any mention of Petit Godin. Searching for Petit Goding parts on the inventex website does turn up a few parts. I could not find another source for Petit Godin parts via a google search either. One might try the hearth.com parts page and lookat woodmans associates.
