Rifle Id?

I bought a cheap China Side lever. Can;t find anthing on it. I think the under lever Is called a B3 but what model is the under lever?

My barrel had a rust ring in it and cleaning it did not remove it so after whating the English chap show how to use a boot lace I didd the same thing. Barrel is clean and shiny all the way. I almost have it sighted in at about 20 yards. It is a pain in the butt to load. but I do like the side lever.
Thanks
