Model 612, described as "Auditorium size, genuine mahogany back and sides, white, mountain-grown spruce top, solid rosewood finger board on three-ply, warp-proof neck, rosewood bridge with bone saddle" in the original catalogue. It's a classic jumbo 12, 15 1/4" wide, 4 1/4" deep, in excellent playing condition. You don't see anything like this very often. In fact, I've never seen one before. The scale is 25 1/2", tone is fantastic, with a big round laminated, three piece neck and ladder braces. The rosette and pickguard are decals, and it's a tailpiece/floating bridge configuration.
