I must have built a million of those things. Air Horn warpers. Secondary well plug leakers. Certainly needed some tweaks.

here is a pretty good source of information on these. I am just learning them myself. http://www.carburetion.com/quadnumber.htm
Well,,, maybe not. I can't actually find that one there. But I think FED is correct. I found several sights that decode the numbers.
