Well, when I got my Toyo 45A, I tried to marry it to this Commercial Caltar 305 mounted in an Ilex Synchro #4.
From the looks of it, I don't think this combo is going to fit on the end of the Toyo (I still haven't gotten my copal 3 lensboard in the mail).

Consequently, I'm going to start looking for a new portrait lens or smaller shutter, preferably something less than or equal to 12" because I don't have enough bellows.

I figured this is the best place to find out where to look.

Thank you so much,
JJ
