K brakes

Group I have a question regarding the dates of K brake phase out.

I know K brakes were banned from interchange in/about 1953, but when were K brakes banned from new installations and heavy rebuilds?

If my sources are correct:

1933 -  Type AB brakes required on all newly-built cars.

1937 - Type AB brakes required on all newly-rebuilt cars.
