I have two snorkels I want to combine into one. The below picture, the bottom nib has a broken tine and the top has a bad section. The Feeds don't fit into each other's section otherwise I would just switch them out. How do I remove the nib from the feed to switch them out?

You may not be able to move the nib from one to the other. As you found out already, there were design changes along the way, and the diameters and threads on some were different.

The nib should unscrew from the front half of the section. A little heat on the nib will help. Hold the threaded end with a piece of fuel line hose or rubber tubing and a pair of pliers. Grip the nib with a piece of rubber or wear rubber gloves.

But say it again, it's quite possible that you will find that the threads on the two pieces are different. In which case, you'll have to keep looking for another nib.

You just discovered the secret of Snorkel sections/nibs. The bottom nib comes from a first or early second year pen with the 14K snorkel tube. Its section is longer and correspondingly its nib holder is shorter than the later year models (the one on top).

The Snorkel nib will come off the nib holder. There are short fine threads. It will need some gentle heat since it is probably shellaced, but you have to be very careful not to grasp the nib by the shoulder or you can actually tear the silver if you turn with enough force. (Don't ask me how I know! )

So grasp the nib by its base (as close to the nib holder threads as possible) and turn the nib holder itself. There's not a lot to hold onto, but it can be done with care.

Thanks,
It looks like both nibs and feeds are the same. I switched them out, and found that apparently I need to add a little shellac to keep them in place, since exact alignment seems to be necessary to keep ink flowing.
