Bonsour all,
I think that I/we got it. This is the reverse side of the strikes. The boards can be fliped over to see the Obverse side of the strikes. Each board is 2 feet X 4 feet. And is 1/4 inch oak plywood. Each board holds 128 strikes. For a total of 256 strikes.
I was bringing them in the cabinet I had especially made for them, to the convention last year. That was when I rolled over my truck on the way to the convention. The boards surived the accident a lot better then the special cabinet, for them. I was going to bring this set up this year. But the cabinet repair shop. Hasn't got the cabinet repaired in time. And I donot have a truck to haul it in yet. Maybe next year.
See you all at the convention.
Dan
