I have a little theory of Gerrish dating his canoes. I have started a list of Gerrish serial numbers which is at home and I am on my lunch at work now. I don't believe that he started numbering his canoes during the very early years. During the mid years of business is when I think he started numbering canoes. I have 5 Gerrish's and no one can tell me for sure dates so I approximate to the best of my abliity of the years. I have not found one with open gunnels serial numbered. So I figure he changed his canoes to OG in 1905. The latest serial number I have found is one of my own which is 1774 if memory serves me. I date it around 1900-1905 so I would guess that the your canoe would be around 1895. How bout some pics of her!
