My apologies to Jay. He asked me the question and I checked catalog copy for No. 5s, but failed to read Houchins' chart on p. 426 which states 24-26 lpi.
If someone would take high resolution ultra close up full size pics of No. 5 checkering and send it to revodc2@cox.net by jpg attachment I'll post the images here and on DoubleGun
