Larry, I think Charlie Pate has a personal data base on these guns. My guess is that probably 2 doz. of these are known to collectors. The only way you find out is by lettering them, as there are no marks or stampings on them to indicate the Rev. Cutter service. I have a list of all the serial numbers shipped & dates. There's approx. 140-150 guns on the list. Many years ago Roy Jinks ran across a shipping record on about 1/2 doz. of these guns. The entry said " Rev. Jones, etc. " giving the name of each cutter that the guns we sent to. Roy was puzzled by the entry and wrote a short note to some of us and a blurb in the S&WCA News Letter about a shipping record entry of 1/2 doz. NM#3s that apparently went to a bunch of well armed preachers! Loren Mitchell, our resident expert on NM#3s at the time, eventually dug out the info. that the guns went to the Revenue cutters. Ed
