the prodigal corkscrew returns

some time ago, I wanted to buy a rather expensive corkscrew, and sold a silver overlay piece to Peter to fund the purchase.  He gave me a fair price, and I had buyer’s remorse the minute I dropped it in the mail.  It was stunning.
 
Well, as luck would have it, Peter has begun to sell of several of his pieces, and I asked if he wouldn’t mind sending it back to me for a fair price.  So, a deal was made, and the corkscrew has arrived back in Chicago.
 
As handsome as I remembered, it looks to be a theiry and croselmire 1886 patent, where the silver was applied, and then sections cut away to create a decoration.
