I just got a very nice Wuttenberg M-95, in perfect condition, but I'm trying to decipher the maker's inkstamp. At first glance I thought it was Gustav Reinhard, as it looked rather like theirs, but on cleaning it isn't. The first name is unreadable and the second seems to start with an 'R', though I can't be sure, but end with '..richt'. 'Berlin 1914' is clear enough. It is in a double ring, as shown in the photos.
