Anybody know if there are any manufacturer variations in corny keg dimensions?

I know Coke pin locks & Pepsi ball locks are different.
I was wondering if there are any ball lock kegs that might be slightly smaller in diameter, I'm talking about an 1/8"-1/4" variation. Maybe one manufacturer to another? Or the single handle version vs. others.

From the ones I have seen all the ball locks seem to be the same. Even the old racetrack lid ones. Pin locks I have in different sizes. The firestone coke ones I have are 23" tall. I have a Cornelius pin lock 22" tall. And I have another 22.5" tall.

All the ones I've seen seem to be the same as well. All 8 of my ball locks are within 1/16" of each other in diameter, and I have a very broad assortment of brands and models.
