Yeah, JimG, that's definately a misprint or wrong pic. DVD I'm sure knows the difference - they've just screwed up that page. The serial # in the pic is something like xx187x45, not even close to the item description #; same with the lens pic and item description - which means, they're not trying to pass a Zorki.1 off as a Zorki.6. They just messed up the ad.
It seems their title [and you] are correct about it being an "e" though. My eyes aren't great, but the first two serial numbers look like "55", it has new shutter speeds, etc. And an Industar 22, not a 50 [I think I see.]
I've got a Zorki 5 en route from Alex-photo. If it arrives looking like that, hey, I'll take it and call it a 5. 😀
P.S. "Showers with spiders"? Cancel our coffee meet. 😉
edit: Ser. # match the Zorki.6 listed above this Z.1.
