Good for you, but you should have been calling it a /16 and not a Class B. (Even if it did come from 128.0.0.0/10)
We were given a /16 out of the old Class A space by RIPE in 1995 as part of an early adopters testing program - and since all our routers were Unix boxes[1] running gated, it "just worked" and we immediately started to use it for our customer connections. Maybe life was simpler back then.
Just let the old classed system die in peace or left to the ramblings of the history department.
