~ Vintage NOS Race Face Howitzer BB/BBa/73/73a x 136mm Team Bottom Bracket ~

I have this Race Face bottom bracket, not exactly sure which one it is.

It's marked BB BBa/ 73 73a, BSA threading. The overall spindle length is 136mm.

I am not sure the box is the original one that it came in. BB is new, but appears to have been test fit.
