Rebuilding An Ingersoll Mahogany Bakelite Dollar Pen

[jaceth]

I bought my first fountain pen at an antique stores a few weeks back. I opened it right when I got home, and found that the section and feed were completely shattered, with the nib rattling around in the cap. I (with difficulty) pulled the section out and found the ink sac to be completely deteriorated, and the rubber plug at the bottom (this being the twist-filler model) to be deteriorated beyond repair. The pen is missing its clip and has a few scratches on the barrel, and the brass on the inside of the barrel where the section was fitted is greenish and slightly corroded.

 

My question is this: how can I reconstruct this pen? It's the perfect shape and balance for me and I love the color. I've been looking up nib units from other brands that might fit (as trying to find another Ingersoll dollar pen is out of the question it seems) and the closest contender has been the Sheaffer No-Nonsense section / nib unit ensemble. Then there's the matter of the plug. I'd have to find a replacement for that as wel. The clip is gone too, but I actually like the way it looks without it.

 

What sections / nib units could I use with my Ingersoll dollar pen? I've resigned myself to making a frankenpen, I just want a section that fits and a nib that isn't too bad. Thanks!
