Mike is correct, this is a 90 cabinet. The top of the arch has a little more of a peak than the 21. Also, if you look at the rear, you can see there is about a 1/2 inch space between the chassis and the side of the cabinet and the back edge of the chassis is about an inch from the back of the cabinet. Now, what I cant explain is the shaft spacing. Obviously,  a tone control has been added but the spacing of the two outer controls would have to be widened to match the holes in the 90 front panel.
