I ended up buying a two bottle set which has a 40CF (size B) acetylene bottle and a 55CF oxygen bottle. The acetylene bottle weighs 25.5 pounds and the oxygen bottle about 25 pounds. So the pair together weighs about 50 pounds. had a little portable brazing/welding rig. As near as I could tell it had an MC size (10CF) acetylene bottle (8.5 pounds) along with a 20CF oxygen bottle (13 pounds). A good match given that you typically use oxygen at twice the rate as acetylene. And the pair of botles weighs 21.5 pounds, very portable.
