Hi Dana
WOW!! That EARLY pistol is a beauty.  And appears in wonderful condition. It must have been somewhat painful to have to re-ship it. LOL  
It appears all iron mounted. The iron piercing decoration on the grip and butt area would have taken a long time to complete, being more difficult than brass or silver to work with.
A couple other things I notice:  The trigger guard attaches directly to the stock versus being inlet. An common feature on early guns.  The other is the shape of the grip and pommel.  From a side view it looks round.  But in fact is more oval shaped.  I wonder if this was a common design feature on early Ripoll pistols ?
I've seen an English pistol from about the 1640's with the same shape grip.
Anyway, it's certainly a wonderful example of a turn of the 18th Century Ripoll pistol.  Offer your friend my congratulations. And mention that he is welcome to send it to me for any future safe-keeping.  I'll even pay for the shipping.  LOL  
 
 
Thanks for posting. Rick
