retaining ring for old lens

[medform-norm]

"Medform-norm - I'm sure you mean mm, not cm? A lens with a 90 cm mounting thread would be a sight to see... "

and wouldn't you like to see it!

No, you're right, it's mm not cm - but still, rather large...and hard to find.

BTW Struan is also looking for a large one, 94mm IIRC . It's a real pain that there's no cheapo way of finding these flanges, like going to a general hard ware store and getting a ring normally used for 'tying fly balls to the back of reverted kitchen sinks' and which only cost a little under $5...

I've set my hopes on the next photographica fair in Holland, although the large format section is largely absent there

I'm looking for 93 and a 132 mm rings if anyone has a box of the things lying about. I actually crawled all over a junked electron microscope the other day looking for flanges and threaded connectors that might fit, but all I found was bunch of septums only a lunatic would want :-)

I'm working on plywood bodges for now.
