I finally ripped a chunk from this old relic that has been in my shop for over fifty years. The plywood board was used as a work table top. It has a lot of, (sniff, sniff), history, including a lot of paint spills and spatters. Twelve board feet finished out the floor in my "lawn tool shed". I can't believe the thickness of the pine veneer on top "and" bottom. Probably A-B grade. I doubt you'll find a true 3/4" ply with this much integrity today. Actually, I'm ashamed I used it.
