Bimacon 80 - are they still available?

Hello,

My first post on the forum - an awesome wealth of knowledge!

I am soon to be taking delivery of an M805 to upgrade from my M601. It comes with the Bimacon 75 which is supposedly only good for up to 6x6. I will mostly be printing from 6x7 (hence the upgrade) and apparently need the 80

Are these still available? I have scoured the internet. Tried Northern photo but they're all out.

Will I get noticeable fall off on a 6x7 if I use the 75?

Thanks for any help
George

There is one on ebay right now but not cheap, from Germany. I am not affiliated, I was just curious.
I have both condensers but I never tried using the 'wrong' one.

Turns out they are like hens teeth or extremely expensive. Luckily I was following an 805 on eBay which was removed. Emailed the seller and bought his for a fair price.
