Now, this is a cool guitar.  I can't figure out how old it is since it has a serial number on the headstock that doesn't make any sense according to Gruhns.  The number is way to high since any Gibson accoustic with this number would have been made about 15 years after I first saw this guitar.  The Gibson decal also indicates it is quite old.  There is a hand engraved number under the broken pickguard (Thanks Katums) and some other number stamped inside it.  My cousin though it was from the 30's.  I wrote most of the Arbitrary's songs (that I wrote) on this guitar.  It's 3/4 size so it's fun to play but the action is really high.  It's kind of beat up, but it still sounds really nice.
