Real interesting 'cause of the flash arrestor; perhaps nostalgic is a better term. Best beer bottle opener Colt ever built!
Seriously, it's very early,( read that, unusual) to see a SPI with the 3-fingered flash hider. I've only seen one other.
In my area, Central Texas, I'd expect to see a $1500 asking price, and a deal around 12-1300, on a rifle of 95% or better finish, and all original Colt pieces.
It will never go down in price- they ain't making any more!
