I guess it'll be a longshot to identify the two signs that went on this Erie 77 pump. The upper diagonal sign was approximatly 14 1/2" wide, hole space is 13 5/8"x 3".
The bottom plate is approximatly 10 3/4"x 12" hole space
9 1/2"x 10 3/4.

Google it you will find super shell diagonal with shell logo

thanks guys! that was way too easy!
Mick are those for sale?

Just am image I got off google.these are fairly common,and easy to find.

...check eBay, and try to find ones with screws...the screws used to affix these signs had a square head that recessed into the sign face...

Yep, this is what ya need ! Ed Shaver
