I saw this thread on the 20th and did a search for Moyers on the internet. Found them, ordered a brass trigger guard and spacer. They show up in the mail today the 23rd. I had them polished and installed by 1600hrs. It took about three hours, including the time to dismount and remount the new parts. I had never taken one apart before so that took a little time. The FAQ section really helped. I would have liked to have spent less but I love the look. I found them easy to fit and polish.
I have a 16ga that I'm changing into 50/70 government carbine. A vintage steel butt plate, brass fittings, a saddle ring, buck horn sights, a modified hand guard with a barrel band and spring, and a barrel liner. It's starting to look circa 1871. love it.
Great sight.
