I can't believe it, they've only gone and changed the letter designations!

That is confusing...
You could also try looking up Hoyarex filters which are supposed to be 75x75mm. Apparently, they were said to be better than Cokin but they lost the fight in the battle for filter supremacy.

The Lee Seven5 series meet your size criteria but are not cheap

I’d be tempted to trust the manufacturers:

“ 67 x 72mm (rectangle filter), 67 x 67mm (square filter)”

The A series is now known as the S series. From memory they added to the number of size options over the years so I’m guessing they moved to a more logical naming system .. S for small, M for medium, L for large and XL for extra large.

The current M series was P back in the day, the L was Z-Pro, neither of which is very helpful I guess.

Default Cokin Filtersl

Coking filters come in 2 main sizes an 'A' series and a 'P' series the P series such as the normal colours are 8.2cm square with special filters such as soft focus, graduates are 8.2cm by about 9 cm. ( I did not measure). The 'A' series are quite a bit smaller perhaps 6 or 7cms.

Being made from acrylic plastic they could be prone to scratches but when not in use so long as they are kept in their cases there is little risk. I would think mine are around 30 years old and still pristine although the cases are badly marked.

The down side I have found is they can be prone to flare because they cannot be coated. Lens hoods seem to be quite rare and not as easily found as the filters.
The 'black' i.e. opaque, infrared is really very good with IR film.

Lee filters are as it has been said, 'not cheap' but the company SRB film services, (or whatever they call themselves today) which used to be based in Luton, will if you ask them nicely, make 'one-offs' and may well be quite a bit cheaper than Lee.

I've used both the A (now S) and P (now M) series filters pretty much since they were first made 1978/9. Never had any problems with them and they certainly last well none have any marks or scratches.

You'd need the P/M series for your Mamiya 645 Paul, the A/S are too small.

It's their flexibility that makes them so useful, mine get used for LF work although I tend to really only use the Green filter but also carry orange red, and a Polariser. The Polariser is actually glass and is (ir was) made for Cokin by Hoya.

I have bought Chinese equivalents, one a dark red to cut to make an enlarger filter for an old pre-WW1 Houghton King horizontal wooden enlarger. Seemed sacrilege to cut my spare Cokin P Red so I went for cheap and cheerful and was surprised to get a filter equal in quality to Cokin or Lee.

Unfortunately one of my lenses needs the X-pro series and the filters are an arm and a leg

I just had to look this up - a wooden AND horizontal enlarger?

https://www.camera-house.co.uk/produ...-only-for-hire

After checking out the image, it looks like it would have originally been illuminated by a candle or oil lamp or something similar?

I wonder how long the exposures would have been, what with the slow speed of emulsions as well?

Sorry for going slightly off topic...

Terry, isn't that the one that had a timer which had marks on a clockwork driven dial based on the time taken for Scrooge to eat each spoonful of gruel? This being an improvement of the older method of reciting "One humbug two humbugs etc

Sensible answers of which the above is not an example would also be welcomed by Terry and myself

I don't think early Bromide papers were much slower than we have today.

My enlarger is quite similar but not identical, but obviously made by Butcher for Houghton's. Mine will take 5x4 condensers but came with Quarter plate and the negative carrier will accept larger holders of course unobtainable now
