Here's one I rebuilt from a broken to pieces Duofold. I made a new cap and barrel and had to rebuild the section because the grip part of it spun freely, making it hard to screw the section into the barrel.
You can see a section part way disassembled here.
I built a new black grip and brass threaded tenon. I reused the nib housing and rings.
I made this one as a gift for a radio personality that I really like, but it's too big for her hand so she's sending it back with notes for me and I'll be making her a slimmer pen.
A Shinobi that I need to remake today with the front of the barrel in the same burgundy material.
Piston filler Sumpter.

Here's an Orville I'm really happy with.
And a Moody built in a similar way.
Moody in a vintage celluloid.
Another Moody in an Italian plastic, Pelikan nib, and piston filler.
A very colorful Prospector.
And one of those Shinobi pens.
