Thanks for the replies everyone. Here are a few more pics and dimensions. With items like this I'm not a huge stickler when it comes to condition. It's rare enough that I'll happily live with it one way or the other. I think it looks great regardless.
The edges don't look ragged at all. It's a smooth cut on both sides, just not precisely straight. There's no unusual discoloration along the edge.
It measures 29 inches long and 10.5 inches at it's widest. I didn't try to stretch it or flatten it so it's possible a 0.5 inch was lost to "shrinkage" or wrinkling. At the "B" it's 6.5 inches wide and at the "S" 2.5 inches.
It's the lack of a border at the "S" that first got my attention. It diminishes quite a bit from the "B" to the "S".
Thanks again for the responses.
