Do I see stitching along the lower edge of the saddle? That is, it's two layers of leather stitched together? Certainly not a good sign. I have an East German saddle that's made like that, and it's pretty terrible. But perhaps we digress; the one on ebay didn't have that stitching, though the top is clearly reenforced with something, which may or may not be a good sign.
I remember the saddle well enough that I'm quite sure that was a stamped-in design, not stitching. The only second layer on this saddle was the second strip underneath the main triangular section as you describe, and that was riveted in with the main section of leather, not stitched.
