I got this drum at a gun show a while ago, ~1995.  It holds 120 rounds, opens like a clam, drop the rounds in and close the back cover, then wind up the spring.   I used it a couple times, it fed very well.  The rifle got pretty hot though.  It gets expensive when you shoot 120 rounds per mag.  My question is, who makes this thing, whats it worth, and is it a good toy to have?

If it works, sure it is a good one to have.  Not the best, but not the price of the best either.  I have several of these mags (Chinese Norinco) for the AK-47 and they have never failed to work perfectly.  The ones for the AR-15 usually sell for between $150 and $300 from what I have seen, but prices right now fluctuate a lot and they are worth whatever you can get for them.  When new and before the ban, they sold for somewhere around $50, so you can see, they are not really high-dollar mags, its just the mag ban has made them so.
