61-62 Cooling System By-pass & Balance Hose Clamp Markings

[Rick C.]

Does anyone know what markings are on original clamps for the pressure balance hose and by-pass hose clamps? The judging manual says clamps are type B or type D and describe the screws but are silent on clamp markings. Pictures make me think there's something stamped on them but they aren't clear enough to tell what it might be..

Thanks!

How about this .... Does anyone know if the edges of Corvette solid axle clamps were scalloped or had "notches" as in these two pictured here. And I wonder if the earlier clamps had the size in inches stamped on them and later ones had the size number. Any thoughts on this and if true, what the time frame was when the change took place?

Much thanks for any information!
