I see a couple not selling on GunBroker for $1,600 plus. They’ve been relisted multiple times.
Rock Island sold one in April of 2010 for $1,380.
In my experience selling, if you list it enough times it’ll sell even if it is 10-15% overpriced. Someone will come along that MUST HAVE IT.
Since they’re not selling at $1,600, I’d say they’re worth about what they were in 2010.
It would probably sell eventually for $1,400, quickly for $1,200, and immediately for $1,000.
