Shimano A/73 REAR brake straddle?

[Oscarsbowl]

Has anyone got a Shimano A/73 straddle marked REAR? That they could sell.
I have two stamped FRONT with A/73 on the other side. If one exists I would like a rear one to help compete a retro build. If so name your price but please be reasonable

A/73 is the length.
There should be no difference between front and rear ?

What brakes ?

Rears are often longer. I have both the A73 front and B82 rear. PM me

of course M734/650 use the A, B setup, others like M651 would use the C D setup (106 / 93) and M900 both use A/73


but A/73 is the same, front or rear.
