FYI, there are 5 Orions listed at the
Zenit archives. (this site is part of the reason I can read cyrillic characters, kinda useful when half your lenses are Ukrainian).
Orion 1, 200mm f/6.3, 92°
Orion 2, 150mm f/6.0, 80°
Orion 20, 200mm f/6.3. 65°
Orion 15, 28mm f/6.0, 75° (for 35mm)
Orion 18, 100mm f/8.0, 60° (process lens)
There's nothing particularly special about them, they're not the sharpest lenses in the world (and certainly not the fastest), there's not much that justifies the prices they get (eg $200ish for the Orion 15) except rarity.
Give it time, and Lomography will release a new version of the Orion 15, just like they did with the Russar.
If you paid $80 for them, that's a bargain. Clean them up, list one as BIN for $1k if you don't need the cash straight away, and just wait for someone to buy one. If noone does, drop it by $50 every relist. As soon as someone buys one, list the others at that price and just wait for them to go.
Or if you really do need the cash, do a $1 NR on one and see where it gets you, then list the others at $50 more BIN and leave them there.
