Fun history question
 

Below is a lousy drawing meant to represent the area on the case / fan housing where the engine number and type are stamped. Along with the number and type, mine has a 'GT' stamped. Is this a factory marking? If so, what does it mean?

The reason I asked is 'GT' happens to be the initials of the guy working for Grady Clay that built the engine in the '70s.

Here's a photo. This a factory marking?

Greg, definitely nothing like that on my '72 case...engine number looks good for a '72T tho...so should be an original magnesium case. Sorry I can't be more help.

Paul, you know the name 'George Tague'? He's the fellow at Grady's shop that did the engine work. I guess he autographed his work.

Greg, I'd say that's a very good guess. I'm sure I met George when I was there, (think I met everybody in a whirlwind round of introductions)but don't remember him now. Is Grady able to give you any clues?

the GT meant that someday this will be the topic of a 'Great Thread' on a BB. So the day has come!

Sorry, I could not resist.
