Copal E-35 8.5 cm f/5.6
While I'm fairly familar with the (Tomioka-made) Copal-E36 series, I was quite surprised to find out there's also a Copal-E35 lens. Given that its focal length is given in cm and it seems like a significantly simpler design overall (most likely a Triplet), I think it's older than the Copal E36 series. Because of its significantly different appearance, I'm also inclined to believe that it was probably not made by Tomioka, but I can't rule it out as well. I wasn't able to find any record of this lens unfortunately, so if you happen to know anything about it, I would really appreciate it, if you could let me know! Thanks a lot.

Hansa Anastigmat Enlarging Lens 75 mm f/4.5
This lens was supposedly used on one of the early Hansa enlargers by Ōmiya Shashin-yōhin K.K. (近江屋写真用品株式会社) and probably originates from around 1936. While it has "Hansa" written on it, as far as I know Ōmiya didn't produce lenses themselves. So I'm very curious who was the original manufacturer of this particular lens. If you have any knowledge or information on that, I'd really appreciate it, if you can share it. Despite its age this simple uncoated lens (with a 4/3 Tessar design, if my observations are correct) still works really well and while I haven't used it extensively you can see a couple of testshots here as well. I'm really impressed by the craftsmanship it surely requires to get a lens to work flawlessly for such an amount of time.

Agfa Colostar N 42 mm f/4.5
This lens still is kind of a mystery - I don't know exactly what it was used for originally - might have been used in an old Agfa newspaper printing machine. If you know anything please let me know! And if you find a second one of these please do so as well - because so far it's the only one I've ever seen. You can find a couple more of the sample shots I took with this lens here: https://flic.kr/s/aHBqjzxVaK and get some information about it and its history in my Agfa article: https://deltalenses.com/index.php/2022/03/21/agfa-enlarger-lenses/
