Help request with ID on strange wooden folding camera

[nik62es]

Hi, I am Nik from Spain. I have found a wooden camera during a clearout. It has been stowed away for a few decades and I really can't remember anything about it. This seems to be a portrait camera, with red bellows, everything seems to be in remarkably good original condition, but I am not an expert. I found it interesting that the beloow can actually be rotated for vertical and horizontal shots, something I though they wouldn't have thought of all that time ago. It extends quite a bit, to a total of over 60cm. However, the part that puzzles me is the objective : It is marked " Serie C. No. 2 " and " Nordstern A. Rieper, Dresden". I have searched the internet , but to no avail. Has anyone ever heard of that company ? Can anyone make suggestions on where to look ? Thank you all very much in advance for your kind help :-)
