This is driving me nuts - Does anyone know of a sure-fire way of ensuring that I'm buying the right type - WITHOUT having to deal with Ukrainians/Russians and the massive language barrier?
Serial number ranges, other markings etc?

Quick update:
I think I may have found a solution to this problem (read above). The Helios 44-3M lens seems to have 8 blades, MC, it's present, AND it seems to be different to the 44-3 in that the focus ring is further forward, thereby ensuring no chance of rubbing on the camera body/adapter ring.
Thoughts? Looking for responses sooner rather than later, I'm eying a particular lens on a particular forum ;););)
EDIT: Damn, looks like the 44-3M won't focus as closely (1.5m according to someone's eBay sale). 0.45-0.5 is the standard for the 44-2 and 44-3, I think from memory.
The lens seems to have some detachable section that is used for macro purposes. I don't quite understand it, but I assume that's what is causing the change in minimal focal distance. More info here.

Thanks, the response from the seller is that the focus-ring and the mount-flange are at the same height...
If the focus ring and mount flange are at the SAME height, you'd think it would still rub - Would the focus ring not have to "end" before the mount flange, to ensure no rub? This would allow a very small clearance (0.5-1mm or something) at least, rather than none.
Can I purchase this lens with no worry?
EDIT: Side note, does anyone know what dia. UV filter will work with these lenses (or type, if there are multiple types?)

I am planning on buying the 44-3 however I would prefer not to grind it back. I have a Pentax K-x camera with the official Pentax M42 adaptor ring.
My question is, are certain serial number ranges deemed to be safe? Has anyone else had any experiences with the same setup?
Failing that, I'll probably stick with the 44-2 or 44K-4 (if I can find one in my price range).
