If the headstock logo is original (a big "if"), it is pre-1948. The pickup is non-original and was added - electric Gibsons from that era had pickups only in the neck position (traditional for archtops of that vintage).
I'm guessing either an L-50 acoustic archtop (f-hole model), or an ES-125 where the cutout for the neck pickup was patched up.
Pre-war Gibson sunbursts are also 2-color not 3-color like this one, so it has probably been refinished - if the finish is original, then the headstock logo may not be - and the guitar could be much younger. Tuners are non-original, pickguards (two!) are non-original. Trapeze tailpiece *might* be original.
You may also date it from the serial number but it depends on whether the number is on the back of the headstock, on the neck block, or on a label inside the body. See here: http://www.provide.net/~cfh/gibson.html#serial
Not terribly collectible, so you should be able to get it for a good price.
