I have a somewhat similar marshboat, except it has stake pole holes, fore and aft. Bought if from Cabela's in 1983, it was made in Appleton WI. It was stolen a few years back by some kids.
Taken for a joy ride down the river, sold, and pretty much stripped and messed up. I got it back, but it needs alot of TLC. Hopefully this summer cuz it's a duck Killin' Machine........
