Gvts & testers manual

In 1968 goods vehicle testing was introduced, and recently I was given 2 manuals that relate to this subject
The draft copy of the testers manual produced in 1967

and a later print from 1972

I must say its interesting reading, but then again I would.

The most recent one is online these days, so it would be interesting comparing things like boiler leaks and coal bucket rusted through against missing ABS Lead
