Ilford ULF run - help me understand the sizes

[filmamigo]

I'll start by saying "Thank You!" to Ilford for the annual ULF run, which makes so many different sizes of film available for order. This is an amazing service to analog photographers.

At the moment, I don't have any cameras that could benefit from the Ilford ULF run. (Maybe.... I have a Kodak 3A which might benefit, pending the answer of my question below.) But I am always looking out for intriguing classics and antiques. I will likely add a whole-plate camera, which will benefit from Ilford's run. I really like stereo photography, but many of the classics seem to take 10x15cm film, which doesn't seem to be available. Selfishly, it would be nice to know what films Ilford offer when I am browsing antiques and come across plate cameras...

So, to my question. I am ignorant of many of the film sizes offered by Ilford, and how they line up with common cameras, or older names for these film sizes. I have tried to cross-compile a list of historical sheet and roll films with the Ilford offerings, but I have a lot of blank spots. Could anyone help fill in my knowledge?

Here is my list.

Metric sizes like 9x12, etc are not part of the ULF run because they are readily available anyway, 1/4 plate is a sheet film size as well as glass plate. 12x10 and 15x12 are historic British plate camera size.

5x12 camears were made in India and quite a few come up for sale on ebay

The roll sizes are at the request of some people making large negatives for atlernative processes, and possibly Cirkut cameras.

Ilford's sizes are based on previous demand and requests, in fact they state if you buy enough they'll cut to other sizes.
