What Enlarger does this go to???

I have found myself the proud owner of a 2-1/4 By 3-1/4 glassless negative carrier that I would like to get rid of, but do not know how to advertise for it. It is 8-1/4 inches in diameter, hinged, and registers using four small pins on the bottom. It has the number 2434RN punched on the top.

I have attached 3 pics.

I want to say this is a besler carrier for their 4X5 enlarger. But do NOT know.

Can someone identify it?

my bessler 45 has 8.25 inch circular holders...so would probably work on that one

Sounds like the old Beseler model number. Sure looks like one.

Good Afternoon,

I agree; it definitely looks like a Beseler.
