Beseler 8069 neg carrier for 23C -- What format?

[Kino]

I found a Beseler 8069 negative carrier for a 23C enlarger, but cannot find a reference as to the format it is supposed to handle.

The opening measures 2 1/4 x 2 5/8 inch (57.15mm x 66.675mm) and is obviously for 120 or similar size film.

Anyone know which format this could be?

Official dimensions for RB67 Pro-S are 56mm x 68.4mm
The Beseler 8070 is listed as glassless 6x7cm (2¼"x 2¾") format. The user manual for the 23CII does not list the 8069, but lists the 8070 for 6x7 neg. The user manual for the 23C does not list negative carrier model numbers.

An old eBay ad for the 8069 calls it 'for 6x7'

Thank you! This must be a filed, or opened-up version, as it's pretty oversized.

I found a post by someone who stated,

"I am using the Tak 6 x 7 lenses on cameras with Graflex Rollfilm backs
RH10 is 10 of 58 x 67.7"​

Member Barlow is advertising a number of Beseler documents from the past for sale, so I asked if the Price List mentioned the Beseler 8069. He replied, "The 8069 negative carrier appears to be for the 6x7 format."

Thanks, Wiltw. Much appreciated.
