Hi friend.

Question about the eco air meters I see some have 3 wheels and some have the arrow with two wheel face.

What's the difference between the two?

Also Is one vs the other have a more significant value or collectibility?.

Thanks

I don't know about having more value but the 3 face was for locations like truck stops that needed higher pressure air for tires. As far as I know they dont hurt or help he value. If it has air and water on it then that's more difficult to find. Mine is the only one I've seen around here but I'm sure I might have missed one at Dixie Gas over the years.
