Sorry for the delay in reply--been moving and finally got my dsl!
Yes, the larger loom and silversmithing both were picked up "along the way" though I think it was smithing, in general, that was picked up from the Spanish and silversmithing came even later. I'd doublecheck but, lol, most of my books on the topic are packed and buried, atm.
There was no references cited and, from the looks of it, I haven't received any email in response to my query about the "pre-Spanish" peaches. I'm guessing that either a. the email provided is no longer good or b. there are no references. At this point, I'm placing my bets on the Spanish, lol.
