That does clear up the muddy water between the two gauges and the SAMMI spec.
Thanks a lot.
Hey I just happen to have both gauges, I like the Whidden but, I get it!

The top thin line is where the Whidden .350 gauge contacts the shoulder, the wide smear below it at the bottom of the shoulder/body junction is where the Sinclair 30A gauge contacts.
Picture sux but you get the idea!
