BUT I CAN'T FREAKING REMEMBER WHAT THIS FONT IS CALLED! Please assist!

Mainframe RD Two Laser  Sugerido por jerseygirl 

Not Mainframe, though given the apparent corroded effect from the 600 DPI scan of the source, I can see why you'd suggest it. Thanks for trying, but if you'll notice, the 1 lacks a tail and the 3 has a round lower half. Both DO have flat tops tho...
