I'm trying to collect information for my long term, commercial MLM II project.

From what i understand Lee Speed rifles were generally checkered with flat top checkering. (Please correct me if this is wrong).

Is there a typical number of lines per inch that was used? Was there a standard dimensioned cutter used. (Side angle/bottom flat width etc)
Were they layed out at 3.5:1, 3:1 or something different again.

Any pictures of lee speed checkering you are willing to post would be great too.

Thanks.
Henry.
