I know that these are quite hard to come by and I was wondering what would a run of the mill example of one of these mags fetch at market. Also, was there an importation of these exclusively at one time, or were they brought here mixed in with other types? I just saw one on gunbroker recently for $150 with no bids (I wonder why...) and thought that maybe they really are that rare. Are they? If you've got one and don't mind, tell us how much, where, and when you got yours.
