I just bought a new unopened off set base plate #9957for a T/C round barrel traditional rifle.. That would be the New Englander I believe. I also got four base plates that fit the Renegade, White Mountain Carbine, Hawkins & PA Hunter. Along with a lot of leather for wrappingflints, jags, patches, mops, measures for pistols, etc.. I have not decided if I want to scope the New Englander yet. As for the other base plates, I believe these attach to the barrel and that allows you to mount bases of your choice to them and then the rings, etc.. But I have not looked at them that close. And don't ask why I bought so many things... another one of them accidents..

that is the code number and what they look like Corey .. (the New Englander is to the far right)
