If it truly is in 99% or better condition, $3000 is no stretch. And things in the gun market are getting crazy now, so even more is certainly possible. As I said, an easy sell for $2K. I'm surprised you haven't already received some Personal Messages from members wanting to buy it.

Regarding Coke grips, technically those were used only on N frames, not Ks. Nonetheless, yours look like Cokes and maybe they actually are if it was a presentation revolver. If "Ed" was someone of importance and prominence in the Remington organization, that would be a big plus, so some research there is in order.

I think getting an "Improved" factory letter would be a very good idea.
