Old Town 153141 is a 15 foot, CS (common sense) grade fifty pound model canoe completed between July 1949 and September 1950. It has white Maine cedar planking, open spruce gunwales and a keel. It was painted dark green (yeah I know it's hard to read, but that's what I'm seeing) and was shipped to Camp Chateaugay in Lyon Mountain, NY, on March 31, 1950.
Was that the camp you got it from?
The scan of this record is attached below-- click on it to get a larger image. This scan and several hundred thousand others were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. A description of the project to preserve these records is available at http://www.wcha.org/ot_records/ if you want more details. I hope that you and everyone else reading this will join or renew membership in the WCHA so that services like this can continue.

It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. Feel free to reply here if you have any other questions.
I worked at Camp Chateaugay from 1972 through 1989. They had about 10 Old Town (green) canoes. They were used on Chateaugay Lake by the campers and also trucked to various locations in the adirondacks for trips. They were abused and neglected canoes. I bought this one and an 18 ft canoe for $100.00 in 1975. Both needed new canvas, the 15 ft had broken gunwales and no center thwart. I found a gentleman in Colton NY who recanvased the 15' in exchange for the 18'. (in 1976 or 77)
The wood work on the 15' is all original except the gunwales that are now mahogany outside and ash inside. I also found a carrying yoke that was permanently mounted as the center thwart. I also have an Old Town spruce paddle that is probably the same era as the canoe.
The canoe is now with me at Big Moose lake in NY where I live.
