Of course, and that's what really matters! Out of interest, what is steampunk? Cause so many people have designed some really cool fantasy style revolvers with 'steampunk' in the title. Is it a manga/anime?
My dear fellow, it is not a manga/anime, it is a lifestyle. Honestly, I don't recall how it started, but it has been depicted in several manga/animes, Like Howell's Moving Castle, Steamboy and many others.
