These are Deluxe Reverb baffles. Dimensions are (H) 13-9/16" x (W) 22-1/2" x (D) 3/4". Speaker cutout 12".These are built to Vintage Sound Amps, specs with a full 3/4" thick baffle and T-nuts for speaker mounting, not Studs. Comes with mounting screws. Great for Extension cab baffle as well.  I have 5 available in the following Grill cloth. 3 - Black & Tan, 2 - Cane.

Note the last Black & Tan baffle was built to Vintage Sound Amps specs, but the builder accidentally used studs like the original.
