Crankpin, That G60 Bluehead was a real animal. It was king of pattern for a while. I'd treasure those two you're getting.

The most famous early pattern 60's were the Veco .61, Enya .60, Merco .61 "Blackhead", Webra "Blackhead' .61, OS .60 "Goldhead and Blackhead" and the Supertigre .60 "Bluehead"

I had a bluehead ST .60 with PDP and let it go. Even more smoothness can be obtained with a Perry pressure/regulator backplate and matching carb.

The only .60 I still have is a Webra Blackhead but would love to have a bluehead Supertigre one of these days.
