Here's a nice looking S. S. Stewart American Princess Model 1 for sale at the Banjo Hangout: click here!

Then follow the links there for images.
This is a smaller (10" pot) banjo, more portable for travel. I'm not sure if it's sturdy enough for metal strings.

It seems to be in great shape but it is missing the ebony shims which stiffen the support rod in the pot against the rim; you want those shims in (easily made) before stringing it up for playing or weird things may happen to the action and the tuning.

Cheerily,
Charley Noble
