Welcome, the Federal hull identification number (HIN) format limits the serial number to five digits so Old Town omitted the most significant digit(s). The full serial number for your canoe is 254989. The last three characters of your HIN indicate that it shipped in December, 1984. It is my sad duty to report that most of the scanned Old Town records stop just over serial number 250000 in 1983 so no one here can provide any more detailed information about your serial number. Sorry,
Benson
