Cliff rebuild?

[KJMason]

Is there a way to ID a carb that has been rebuilt by Cliff (other than it works perfectly of course)?  Mine has been rebuilt but I have no idea by whom and it would be nice to know.  Also, I hear a few of his carbs have been listed on E-bay, how do you know it's legit?

I've rebuilt and/or restored over 4000 units since going full time 12 years ago, so some may make it to Ebay or other websites for sale.  I don't put any sort of signature on them, so difficult to tell if we really did it or not?....Cliff
