I have this one as well and it seems to have the same setup (adjustable seatpost, high stem). I bought it in the Netherlands in the summer of 2017 for around 60€. Seller told me the bike had spent most of its lifetime in the garage, so I guess most of the parts are original.
Unfortunately, some vandal kicked the mount for the brake from the front fork, so the next project is finding a replacement fork that fits. Any ideas where to find one? I just created an account here, so I can't share a picture of it.
