Mr Sweeney, on page 165 of your 1911 book there is a chart about the guns that were built up for matches. I was wondering if you have the web address for that website? The only thing I've been able to find says that MIcro rear sights were used in 1961&1962. Since I have a Remington Rand that was obviously built up by a military armorer into a NM gun Iwas wondering if that was true. This 1911 I have looks like they worked it over and it went straight into storage, it doesn't look like a round has gone down the tube.
