This is one of a series of commeratives made for Okla Tire & Supply Co (OTASCO). As the model # suggests, it was made in 1979. This rifle is pretty much a Glenfield model 30A. Same thing as a 336 but with less expensive wood - usually birch. The theme for 1979 was American Hunting Tradition.
There weren't many of these made, but for some reason, they have just not taken off as a collecting category. So, the value would be about that of a regular Glenfield in similar condition. SW
