I noticed on ebay, the authentic lambskin flaps' quilting deflate over time. I don't know why but more often than not, it's the lambskin flaps that look really drab because of the quilting deflating. It's sad, because the gloss/sheen of lambskin doesn't last forever. Even with polishing and extra care during use. It's so high maintenance. I stay away from the lambskin leather. Reissues, however, are distressed already so the wear is not so apparent.
