You are looking for the model not the make. Try searching images online. Search for Texas Boat MFG and also for Texas Maid and scan until you see one with those distinctive gunnel supports.
I had a boat years ago, and didn't even know if that corner cap that said "Crestliner" came with the boat. I searched Crestliner, and eventually discovered a pic of a little speed boat, with a front hood and seats like a car. Turned out, I had a 1957 Crestliner Viking that someone had gutted, cut the hood off, and turned it into a jon boat. It was worth the time searching for it.
I hope you can find which model you have. It's distinctive looking, which may make it easier.
