These are for a full size 1911 and 1 is in ss finish and the other in blue finish. not sure which brand they are but they do appear to be the Ed Brown brand. These have the checkering on the back looks like 25lpi and are the flat piece magwells. Part # engraved inside of the blu one is 864 and for the ss is 755. Just looking to sell them for 35 bucks shipped for each. PM me for pics. Thanx.
