I’ve got one I’d be willing to sell. It’s brand new, never had the amp guts installed. I bought my ED from a guy in Illinois and he ordered the short head cabinet but never installed it. Just remember, if you pull the guts out of a combo all of the writing on the faceplate will be upside down.
It’s the same width as the 1x12 combo but more narrow than a 4x12.
PM me for my email address and I’ll send you pics.
Edit: After reading your post again I have the feeling this might be the same cabinet, but I can still send you pics to make sure.
