<p>Thanks for replies to all. Yes it's an m42 screw-mount. I already own a Spotmatic SP in reasonable (but deteriorating) working condition and a bunch of S-M lenses to go with it, and I was attracted to buy the STL 1000 after some research because it is described as very heavy metal build with first copal fp shutter in an slr (interesting story), I also know Cosina has historically made product for pretty all the major brands, and is the company behind the more recent Voigtlander resurrection as a respectable line of mechanical cameras and great optics. Closing the back with the post out shouldn't be an issue, because the STL has a separate door latch on the bottom plate. I was hoping that disassembly would be unnecessary. I've done this before, and I'm always afraid of losing some tiny and utterly irreplaceable part or bodging the order of reassembly which I've usually managed to work out by trial and error. Anyhow that's what I'm probably looking at. Thanks again!</p>

<p>Hi,<br> I recently acquired one of these for a very good price, however it's got an odd mechanical issue: the rewind post is extremely stiff in terms of popping it up and down to unload/load film cassettes (it revolves fine for actual rewinding). I need to use a butter knife to pry it up from the top plate, so I can get a good enough grip to pull it up the rest of the way. It also requires unreasonable force to pop it back down. I've spent some time trying to work it free with judicious applications of mineral oil, popping it up and down, and spinning it. When I wipe down the post with a paper towel, it yields a blackish residue, suggesting oxidation may be the cause -- there's been a slight improvement, and perhaps if I persist with this method it will obtain a more usable state, eventually.<br> Has anyone else experienced the problem, and were you able to fix it -- speculative suggestions also welcome.<br> <br />Incidentally I've been able to put a film through it (at the lab now), so I'll soon know whether there's anything left of the light seals...<br> <br />Thanks!</p>
