Old Frostie's Root Beer! Wall Clock

This beauty hangs in my garage. Probably not an ideal place considering the Texas heat. It was handed down to me. Would love some ideas on how old it maybe. It is in great shape physically, but the clock or timepiece has seen it's better days. The trim around the edge was missing screws, but added/repaired with what was in the screw drawer. All in all it is a very descent item. It appears to be a 60's or 70's made clock. Any ideas? Look on the net, but only came up with the bottle cap round style clocks out there.
