I had Old Town research canoe serial number 20606 16 and the above is the model type they came up with from their records. However, this model doesn't appear in their 1912 catalogue and they themselves are perplexed as to what the "MC" designation means. They are having a local historian research this further but originally suspected it meant "Morris Canoe" as this was a company that contracted out a small number of orders to OT when their own factory burned down. However, there is some question about dates matching. Has anyone ever come across this MC model designation and know what it stands for?
