Do you still need a Passier? I picked up one a few months ago. According to their website, it was made in the 60's on a Baum tree, AP style. The tree is sound, etc. It has knee and little thigh blocks. It's super cute.
The seat is around a 17", I think. I'm an 18" and it's a bit snug. It looks to be a medium tree, but it just barely fit my mare who takes a bigger medium-wide. Please feel free to PM me if you're interested. It's a great saddle, but my Crosby fits my fat mare a bit better, lol.
Here's a link to some photos I took just after I bought it: http://www.facebook.com/media/set/?set=a.267698149984391.66770.100002326240009&
