I have a circa 1927 L.C. Smith, Ideal Grade that has a Miller Single Trigger. The gun originally came with a Hunter One Trigger and I thought it was sent back to the factory for the Miller. Dan May saw the posting on the L.C. Smith site and responded that Miller did the work. Mine has the selector on the safety like the 3 position safety and was the first style used. Later it went to where the Hunter One Trigger had it.
I have to agree with Researcher that this is the only way to have a selective trigger that is easy enough to operate, and the only one that can be done with the gun mounted easily. (not including modern ones with the button safety on the trigger or left to right safety)
