would vs would have been

Question

In the Soviet Union, bribing government-employed sales clerks to avoid standing in line for scarce items, or just to find out when a shipment of oranges or imported Western shoes would be on sale, was established practice.

Should it be "would have been" here instead?

Answer 1

No, it's correct as is.

It's the past form of "will be". "Would have been" is unreal past. This is not unreal.
