I sold a high-end Junior Gentleman II to a customer who wasn't happy with the ink flow. After trying to solve his problem, I offered to replace the fountain pen assembly with a rollerball on his pen. Easy I thought, screw the old tip assembly out and the rollerball replacement from my spares in. The replacement didn't fit because the threads were different. I assumed my spare tip assemblies must be the original JG, not JGII, so I went looking for a replacement JGII tip assembly. Roy generously offered to send me one, but I decided to pull one from one of my pens to solve this problem. It didn't fit... the threads are on a JGII fountain pen are different from those on a JGII rollerball, and the assembly won't screw into the receiver in the barrel. OK, I have original JG parts including an entire tip assembly including the threaded receiver so I'll tap out the entire end of the barrel and rebuild it. But, the threads on the outside of the tip assembly on the JG are different from those on the JGII, so if I did a swap, the barrel would not screw into the cap. I'm turning him a new pen and chalking this up to experience.
