They seemed to use a lot of that style plywood in those days and in thickness that is so uncommon today like 3/8 and 5/16. You can get Baltic Birch in 10mm and they make it in 8mm but you would have to purchase a whole container to get any. Next time anybody goes back to the old country, ship out some plywood for me, would you?

I have had to make my own plywood several times to duplicate an original grill. That thick layer is tough though it can be salvaged from old radio cabinets. Also I have used my plainer to cut down some to 5/16 less the thickness of the finish veneer. Plaining plywood is a PAIN!
