What to look for in a 1MchZ Sturmanskie?

There's bound to be someone around here that knows the score on these... from my own googling, it would appear that the one I'm after (a Gagarin) is either a 15 or 17j movement, depending on who you ask. And that they both have red second hands, but differ in the crown and internal movement markings (as well as the additional 2 jewels)

What is immediately clear from searching for one is just how many 'fakes' or made up watches are out there. I've seen some 15j movements with 17j parts - and some with completely different movements from what I'm lead to believe it should be! It's a minefield,

Am on a hiding to nothing here? Should I just look into a replica, or do good originals actually still exist amongst all the dross?

And where on earth should I look? eBay doesn't turn up many that look appealing or legit...

It sounds like you're still having flashbacks...

"I seen things, man - I SEEN THINGS YOU WOULDNT BELIEVE!" 😁

There's three here that's caught my eye. I think the first is the best of the bunch, but not sure if the crown is correct. The second the crown is definitely wrong according to the links provided by @Foo2rama.

I remember seeing something on the interwebs about reproductions of these being made at the moment. I believe someone in Germany is spruiking them.

Well, I put an offer in on the first one, and he accepted it. So I'm now the owner of it... first order of business will be a new bund, as the one it's on looks awful.
