I've used the search function, scanned the site map, and found nothing that seems to bear on the sizes of Pacemaker Graphics' lens throats. I know that the 2x3s are 48mm square. What size are the 3x4s and 4x5s?

I also didn't find anything on minimum flange-to-film distance or extension, so here's a table copied from GGP.
