I rec'd some Jr. Gent FP kits in a trade with some friends some time ago.
As I'm setting parts up to turn an FP, and ensuring that the pen will post, since the customer was adamant he wanted posting.
The black plastic part of the centre band coupler on the left will accept threads from both the nib end and the end opposite the nib.
The one on the right will accept the nib end threads but not the end cap threads, consequently it won't post.
So I'm left with not knowing whether I have an incorrect centre band coupler or an incorrect end cap.
Anyone have any ideas to help me out with this dilemma?
