Please accept my apologies for the slow response to Tito Ferradans’ message.
Deadlines are always chasing me down, so I’m unlikely to be the most prolific poster…
I am aware of the amazingly generous work Tito has done with his Lens Encyclopaedia and wonderful YouTube videos. And time permitting, I’d be happy to provide any information which might help his work.
However…
There is someone who can supply much, much more information than I ever could.
His name is Tony Shapps, erstwhile proprietor of The Widescreen Centre in London. This establishment was the largest consumer anamorphics dealer in the world from the 70s through to the 90s, and Mr Shapps was a personal friend of the CEO and owner of ISCO. He also provided most of the information for the Iscorama Wikipedia page, and is an absolutely top fellow by all accounts.
So perhaps someone on the forum should try and open communication channels with him via his Facebook page:

And to Barney909, I’d consider putting the lens back on eBay, but running the sale as an auction. It’s a very rare piece of glass, and if a real ding-dong bidding battle got going, you might even make enough money to buy an Iscorama 42; and a 54.
With enough left over for a baby Iscomorphot on the side.
I’d also be a bit wary of hanging what is potentially a $2000 - $4000 lens off my camera with some cheap filter bodies, so you might want to enquire at redstan.com about a custom clamp.
Good luck…
