There is a small dent into the Filterthread, but i've had already ordered a Lens dent Tool, to fix that issue, and 1-2 other vintage lenses. Overall, the 35 GT is very cute, only the leather case, the pulley at the middle, which locks the camera into place, is being broken into half, 2 parts...such a pity.

Eh, those leather cases are just moisture traps anyway. I usually take the camera out right away when I get one.
You can fix that filter ring dent with a wooden dowel rod (those bamboo skewer sticks you find in the grocery store are excellent, with the tip cut flat), and a small hammer. You place the damaged part of the filter ring against something firm to keep it from bouncing, and then work the dent from both ends towards the center until it's back in shape. When I say small hammer, that only relates to size. It needs to have a head with some heft to it, better if brass in a somewhat larger diameter than would be found on a jeweler's hammer. Even a tack hammer is too light, and the head is not big enough in diameter.

Hi PF, i wouldn't ever use something like a "Hammer" in Correlation with any kind of Photogear. I do use this Tool into some weeks, when it's here:
But i haven't ordered mine from Amazon. Since i do have at least 2-3 Lenses more with that issue, the money is spent well.

lenslover ... I have the exact same tool and tried to use it on a couple of throw-away lenses, but please use some caution when using that type of spreader. It may look like the perfect tool, but they can mutilate the threads with little effort. If you have a strip of very heavy tooling leather that you can use as a cushion... the teeth on the tool will literally chew the filter threads up when you crank up the presure. The 'threads' of the tool don't match lens filter threads in pitch angle or the number of threads per-mm, and it will re-cut mismatching threads at the presure points. The other problem is that it can stretch the ring to be out of round, or worse yet, create high-spots by pushing the two opposing edges of the ring too far. It will be impossible to get it round again and still accept a filter. If you have or can borrow a set of locking calipers, it will at least allow you to check the diameter and shape as you go. I've found it's far safer to use wood, like larger diameter Oak dowels to 'bang' on their side, or as PF suggested, Bamboo skewers if you can't remove the ring first. It's slow going, but it will work with more precision.

lumiworx i've experience with building modeling, soldering, repairing notebooks, and i don't have 2 left hands. I'd attach some grease, to reduce the friction between both parts, and would try this out very carefully, 1st onto a old, damaged lens thread lens, not on my fine 35 GT here..
The "bang" method with wood sounds somehow safe, but it could also get lens elements inside subtle get loose, i do fear...hence therefore then being decentered, which i'd like to avoid at all cost, since the lens isn't detachable, by design.
Thanks for your advise both, PF also.

Well, it's not like you'd be swinging a sledgehammer at the lens. I'm talking something with a head just slightly heavier than a tack hammer. Most filter rings will give with very little force, so it doesn't transmit much to the rest of the barrel. The idea is to not let it rebound when striking the dowel. You can make a cradle with a piece of construction wood (2x4 in the States) and a hole saw the size of whatever lens you are working on. You saw out a portion of the wood, and line it with a little fabric so as not to mar the barrel. By working from both ends inward toward the center you raise the bent portion with less chance of cracking the ring, and the wood of the dowel helps to reshape the threads into proper alignment. I've used this method on many lenses, and never had an issue with loosening or de-centering lens elements. Here's a link to my Yashica Electro 35 GL repair page on Flickr illustrating the method flic.kr/s/aHsjtBaMurPF

I got bad luck with Aliexpress, the Seller scammed myself, 1st time ever into ~10 years on Aliexpress, faked the Delivery Note, so with the Dispute on Aliexpress, i didn't received my Money back, and lost every Penny of it, never had that kind of online fraud, -trickery ever on Ali before. I should have had ordered it via Amazon..more expensive, but then, a better Chance to get my Money back, maybe. Just in case, the worst Case Scenario happened, like into my Case.
