Mark, I inquired about the gun, but it was sold, to you. I thought it was a very interesting gun. I would like to know the serial number so it can be researched at Griffin and Howe. Do you know how to do that? I will check it out for you if you share the number. I have been able to research both of my Francottes through Griffin and Howe. I use the RST ammunition which is quite low pressure and available in shot loads as light as 1 1/8 ounces. You can look at the prices for the RST ammunition on their website rstshells.com . You can't believe how happy I am to know where this gun is. I have several light tens in my shooting arsenal and am always looking for more. Bill Murphy
