Beverage can manufacturing apparatus is provided in the form of a set of N necking stations S1, S2 . . . SN for progressively necking a beverage can body having a diameter greater than or equal to 2.8 inches to result in an open end designed to receive a first standard end. The necking stations are constructed such that a subset of the necking stations Si . . . Sj, where 1<=i<j<N, progressively neck the beverage can body to result in an open end designed to receive a second standard end for the beverage can. The diameter of the first standard end is less than the diameter of the second standard end. For example, the first standard end is say a 202 standard end and the second standard end is a 209, 204, or a 206 standard end. Alternatively, for example, the first standard end could be a 206 end and the second standard end could be a 209 standard end.
