Now you have me thinking--it looks like it needs about a 1" extension. The Wisner body is only 1/4" thick and even thinner where the wood is mortised to hold the bellows, and I don't really want to modify the body itself, but maybe an extension that fits over the outside dimension of the box... I'd have to sharpen my wood working skills and figure out how to attaché the 5x7 back to the body. I still want the 90 degree rotation.

I'll have to think on it.
