Are Logan Change Gears Interchangeable With A Sb 9a?

[PaPa_Jack]

I've been looking for a 56 tooth change gear for my 9A. I have seen a lot of them offered on Ebay for Logan's and Atlases, but none for the SB. I was wondering if anyone knows if any of these other gears are useable?

Take this for what you will, but there is a Logan lathe currently for sale up in these parts that has a SB quick change gear box installed on it. Had to do a double-take when I saw the ad. It's not a staged photo either, looks like the guy has been using it this way for a while.

Measure it, then compare.
