Hello, I just bought a Vintage Montblanc No. 38 ballpoint pen from Germany. The problem is that I also bought a refill which doesn't fit. I did my homework of figuring out what refill would fit the pen. I bought a Montblanc refill 901L M with a blue adapter at end of the refill. I found pictures of the very refill used on this pen. What is wrong? Please help me find a refill that will fit. Found a picture of the exact pen and refill here on the forum (not my pen but exact what it looks like) http://images55.fotosik.pl/3/c745b0321b7fdd23.jpg Thanks Kristian in Norway
