10ch,
Interesting. Looks like a brand new saddle in the photo, no sitbone dents or anything, but I've never seen that finish on one before. Had your friend used it at all? Maybe most people put Proof-Hide on their B. saddles or other stuff to help it break in faster and also to help it be water-resistant- I know I do. You do NOT want rain soaking into the leather.
Is your saddle broken in yet now?
