Hi James,
We have 2 slightly different styles of beaver tail bails, but neither one is pewter.
One of the nice things about beaver tail bails, is that they can be adjusted/bent to fit a variety of thicknesses of items/pendants. But pewter is cast, and so is not a good material to bend.
I think that is why I have never seen a beaver tail bail in pewter.
The two we have are #41-291 (fold-over, starts out flat) and #41-290 (pre-folded, available in 2 sizes).
Both of our styles are available in basic white plate and yellow plate.
