Thank you everyone! Unfortunately not much readable info on the box. It appears to have been well-loved by a large thumb for many years. I checked back with the gentleman I purchased it from, who also restored it, and he dates it to the 1950's. I have no idea how or why but I do trust him very much. It will be a nice Cmas gift for my grandson. Thank you!
