That serial number format doesn't seem like an Old Town so my guess is that you have a White Challenger model that is 16 feet long from 1950 with their serial number 1286. There are no known White serial number records available so this guess can't be verified. Several White catalogs from this period are available from http://store.wcha.org/The-Historic-...pany-Catalog-Collection-Version-2-CD-ROM.html if you want more details. It looks like a nice one.
