OK, that is a reasonable expectation. As regards the saddle in question, it is described as brand new, so the scratch seen was either:
1) present when it left the Brooks factory; or, 2) damage that occurred post-manufacture. I doubt #1, because Brooks saddles are closely
inspected before they are shipped and while leather is a natural material that may have "imperfections" those imperfections are usually
things you would see in the graining of the leather and such things as healed hide injuries sustained during the life of the cow. These
blemishes will appear beneath the finish of the leather. This appears to be ascratch sustained after the saddle was shipped.

I'm sure that Brooks would be interested in knowing if they shipped a defective saddle (even if it is a cosmetic non-functional defect), and
if so, they would undoubtedly replace it for the buyer.
