One of the bikes that recently strayed into my stable came with a bottom bracket that looks to be Magistroni, except it doesn't actually say Magistroni. There is the familiar "Nik-Crom" on the cups but the only other identifier is a logo that has "AM" within it.

Does anybody have an idea of what the "AM" stands for?
