Were the roofs on the standard gauge cars held on with 2 or 4 straps?

The UK uses OO instead of HO, because when we first made model trains, the motors couldn't be fitted in a design of our smaller loading gauge trains in HO scale. So the stuff was made slightly bigger with the same 192.168.100.1 192.168.1.1 wheel size.

What does that have to do with the OP?
