Where are the accessories Aero's came with ?
I've NEVER seen a heating ring or a filter flange F** S** anywhere, auction site or else.
Why ?
Dumped ?

I see filters and sets occasionally on wepray.

I'm not sure what you mean by filter flange. Aerial camera filters are usually bayonet mount and spring-loaded. I'd swear I've seen filter sets for 7"Aero Ektars, also 7 inchers with filter attached.

I don't think I've ever seen a 7 incher on offer with heating tape attached but most of the B&H 6 inchers offered have it. A couple of EKCo 6 inchers have recently come to market. They differ from the B&H versions in two ways: they have a diaphragm, the B&Hs have been fixed aperture, and they don't have heating tape.

FWIW, the 38 Biogons I extracted from AGI F135s all had heating tape wrapped around them. It was glued on.

Against this, Uran-27s and Orion (no number!) lenses on AFA-39s often have an attachment with heating wires that attach to the front.

Dan, remember it's not my language.

Gosh! Not in my language either. Did you find it attached to an Aero Ektar?

I wish I had, Dan.
