Nice find Randy! It even looks to still have original neon in it as well. A challenging removal always makes you appreciate them more. I have a couple of Bullseyes in my shop right now if you have any other questions.
Actually that's a different clock. The OP has an Electric Neon Clock Company - often called a "Cleveland" as that's where company was from. The one on top of Texaco station is a much more rare Federal clock. Both great clocks. Enjoy your cleveland!
