Very nice piece; can you show the whole set??
Identify Set
At the minute it's at my parents house, I just got a few quick pics while I was there. Recheck the link and use the arrows I'll upload the photos I have

Their image sucks but it looks like the following set:

The following site has a better of a picture. Though, from description of the product, their version didn't come with a nice board.

The best known manufacturer of metal chess pieces is probably Italfama, and I hope I spelled that right. Ebay often has sets and some of the online chess stores carry them also, but of course there are a lot of other lesser known brands as well. Pretty set. Here's an Ebay listing (used) that may be your set.

Stupid link doesn't work, but get to the chess category in Ebay and type Italfama and it will come up.
Can anyone give me any more info on this set left behind by my grandmother.
King piece looks to be Napoleon
