EBay is your friend. I got mine doing a search just like what Hermit John suggests above.
Don't buy the first one that comes along, watch the market for a few weeks. Some are quite collectible and fetch a price reflecting that. Others are rusted junk. Some will be not-so-collectible and in sound condition - that's what you want to bid on.
Can't recall how much I paid for mine, but it wasn't much as I recall. Looks like it's a hundred years old, but it's solid.
