That is a Montblanc 149. Amazing pen, Montblanc's top of the line. You'd probably be able to resell it for close to $450 USD today, provided it's in working order. I'm unsure of what year that one is, but someone will be along to confirm its age shortly I'm sure.
How much did you pay for it?
Also: I can tell that the feed is misaligned with the nib, as it peeks out from behind the nib in the first photo. So, that will require some professional service to correct, most likely, but in my opinion it would certainly be worthwhile to have it put back into working order. Make sure the piston turns freely and smoothly, as well.
