Anybody recognize this airplane? Wingspan 72 1/4" tip to tip, fuse is 56 1/2 nose to tail, balsa built-up cowl. I'm assuming its a Dave Patrick by the stamp, but unsure of model or age. A friend picked it up at a garage sale, with the OS 120 Surpass and an older Airtronics radio system for a almost nothing. I'm in the process of covering/recovering it. It was never finished, and therefore has never seen the sky.

How about it fella's? Any ideas?
