I have the Nettar 518/16 with double exposure prevention. I've yet to put a roll through it, but it has been serviced and is ready to go.

My great grandfather had one of these. The f6.3 version to be specific. He used it to take my mom's baby photos. My grandma sold it and all his other possessions after he passed and she moved away from Slikkeveer to Dordrecht, but she kept the manual so I know which one to get. Sadly the f4.5 is easier to find and its not as cheap as people claim. so I need to keep an eye out for one.

Sweet old camera. Lots of nice locations

Really nice B&Ws. Of course, your expert developing would also make a difference.

Mikael, some nice photos there. I have a 518/16 Nettar, and fortunately mine has the "Red Window" double exposure prevention system which makes it a "Signal Nettar". I've not yet shot my first roll of film, but I want to soon. But I have a question for you. When I look inside my Nettar, like yours, I see no evidence of light seals ever having been there. And I looked at another one owned by a local collector, and it had none either. If you can explain what you did to fix the light leaks, I might try to do it in advance on mine rather than get light leaks on my first roll. I think you said it involved tape and possibly something else. Thank you.
