reverse board and batten plywood siding

[Tim Lee]

I have a house I'm rehabbing that the exterior is in good shape except the prior owner had a window a/c through the wall right next to the front door. I need to replace 2 pieces of 4'x8' 3/8" thick textured reverse board and batten plywood siding with 12" O.C. 1" wide grooves. Everything I'm finding now is 8" O.C. w/ narrow grooves. I've tried everywhere I can think of and internet search. Does anyone know of a source that still makes this siding. It was common when this house was built back in the 70's. Thanks
