BMA Assemblies were introduced in 1966 and ran until 1988. It's not
clear how these assemblies differed from the A- (Assemblies) or AX- (Misc Parts
& Assemblies), but.. they must have been introduced as part of the
organizational hierarchy, as TMC products became more complex. There are
no drawings for the BMA's. BMA's could be included, or be included in,
other types of assemblies, could be part of other BMA's, or stand-alone.
There is a definite pattern of pairs of BMA's, "Subassy" with neighboring "Final
Assy" at roughly the same date. One possibility is that a BMA exists
simply to create a Bill of Materials (the "BM" in BMA) for one level of
hierarchy in a system design.
Altogether, BMA's are a bit of a puzzle. In the unlikely event that
anyone ever reads this page, and you can shed light on this TMC oddity, please
let me know at
