I was once interested in a very rare item from Arsenal, a Red Flag Chinese M4 copy with lenses. I've always wanted one, and I feel with the rise of China as a monied collector's country, the Red Flag would one day be worth a small fortune.
I once missed a chance at a camera show to buy one with all three lenses for $4500 because I didn't have the funds at the time.
I then noticed that Arsenal had one on eBay for quite some time for about $17000, which is absurd. Past known sales prices were anywhere from around $6000 to a high of about $9000.
I made them several substantial offers near the top end, and they wouldn't budge an inch.
We never came to terms, but they seem to be pretty serious about their prices. I guess they sell enough at their outlandish prices to desperate or overly well-heeled collectors to justify their prices.
I've always wondered how they aquired their rare stuff, they seem to have enough of it.
