Lost a piece, trying to figure out what set I have

I appreciate any help identifying what style pieces I have. Thanks in advance!

It looks like a set sold by a number of vendors as the "Big Knight" or "Executive" set.  As here ---->>

Edit: How do you like that set?  Have you had issues with the weights coming loose?

Yes, many of the weights have grown loose in only a year or two. The set serves its purpose, but I could go for something a little nicer

That was my first chess set years back. It's leaps and bounds better than the small plastic peices I played with growing up, however after getting my first nice wooden set I've never looked back. If you think it's time for an upgrade I don't think you'll regret it.

You should try making your own pieces, preferably from metal. That was the solution of our high school. Pay attention to white's b1 knight.
