The mystery canoe

Hello! I recently purchased an older 17’ aluminum canoe. I’m looking for some more information as it’s a bit of a “mystery canoe”. The HIN that is stamped on a plate is only 10 digits, which makes me wonder what manufacturer made this canoe, as well is what model/year it is. Any and all information is great fully accepted. I’ve attached a picture including the plate with the number

WAG, since it starts with a ‘G’, Grumman?
