And the mystery deepens!!! :-)
I am sorry, just shows you I don’t know much about fishing rods.
Had to make one last dich effort, I put the image with the writing into google lens. This is what came up, a different manufacturer. Good luck.
The item in the image is a vintage fishing rod, likely manufactured by Heddon, featuring a water rub decal with model and sizing information.
Model Number: 1510.
Size Rating: 5.
Decal Style: Water rub decal, common on vintage rods from the mid-1950s onward.
