I have seen these at guns shows for around $1,800, NIB. The spare 22 cylinder can bring up to $400 on the open market, but it is probably numbered to the gun and you would not want to sell it anyway. I paid $1,200 a few years back for a 1st year 6" M53 NIB, only because the serial number was K 444444. No 22 cyl. About a year later, I paid $1,000 for a NIB, last year of production, with the 8" bbl. I bought these with no intention of ever firing them. Just a good investment. Big Larry
