The Red Dot Blocks. They had the most material between liners. I think they went into P38's, which is why Block/Liner issues aren't a famously bad issue with P38's like they are with Disco's. Blue Dot blocks which had less material between liners or the liners were not evenly spaced, went into Discos, of course.
The factory had Yellow Blocks as well...they used those when they ran out of the Blue blocks. Probably ALL went to the NA market.
Yeah, and yet when you ask the so called "experts" in the field who are slapping these things together, none of them think it matters...
Dip-shits. This industry needs an enema, and people who have the balls to call a spade a spade.
