We have recently inherited a couple of Mont Blanc pens, one of which is a Nobless Oblige. It was in a filthy state, but I've cleaned it up and it now writes beautifully. But...
The cap does not close.
I've looked down the inside of the cap, and there doesn't seem to be anything out of place or jammed in there. I suppose it's possible that the Nobless Oblige cap is not original to the pen and that the barrel and nib are another model. In fact, if I were seeing this 'in the wild' that would be my assumption, as the gold rim at the back of the section seems to be slightly too wide. But knowing the former owner, I think that is unlikely. So I'm stumped. Any ideas?
I'm including some pictures below. The first is a close-up of the 'most closed' position - note the gap. The final picture shows the pen as a whole. The top of the cap has a slightly rounded MB white star; the bottom of the pen is flat black. Sorry, no photos of the inside of the cap - I don't have the equipment for a picture like that.
Thanks in advance for your help.
