Earlier cars had just 4 bolt holes, with captive nuts behind the holes.
They were filled with chromed rounded hex headed bolts.
Later cars didn't have the holes at all. I don't know the changeover
point offhand.
I don't know what kind of "competition windscreens" used the kind of
mountings you describe. Original Brooklands screens used just one piar
of holes per screen.
