Our off-color red bricks are from the 60s, and the plastic they are made from
seems to be at least as hard as ABS, so they aren't made from this third, softer
plastic. They are most likely CA, but the fact that none of them are warped is
suspect. They all interlock well with ABS bricks. It's just that they don't
"grip" very well.
Speaking of bricks with the old LEGO imprint on the studs, we have lots of them.
They appear to be ABS, as you mentioned. These are probably mid-60s bricks.
