Thanks for the reply! I wrote too soon, it turns out. The turnlocks are loose on both, but I did not check the second one before typing. Its turnlock IS sewn through both pieces of leather, thus accessible.
I didn't bother authenticating here b/c the pic of the first one's stamp did not show it in full; only the middle section. I bought it on Ebay from linda*s***stuff, who has been good with returns, so I don't see a problem sending it back. However, I just glanced at the listing now and they state it's been authenticated by My Poupette, "the world's oldest online authentication service!" I've never heard of My Poupette, btw, so can't comment further on this.
I'll take a pic of the entire creed and upload it later today.
