I have a 4.5" O-ring pony snaffle and a 5" grazing bit, both of which have never been used.
I also have a 5" Tom Thumb and a 5" D-ring twisted dogbone snaffle. Both are a little rusty, but have no sharp edges.
Shipping won't be more than a few dollars (unless you live outside the US).
If you put the $10 in my PayPal (firstname.lastname@example.org), I'll ship them immediately and let you know what the shipping cost was so you can pay me back for it. That saves me an extra trip to the post office, and you'll get your bit faster : ]
