Willard NP-15-3 Navy Standard Battery 6 Volt, 15 Amp Hour Lead Acid Flood For Sale

This is an "old" unused Willard 6 Volt lead acid battery. The model is NP-15-3. Not sure the year it was manufactured, but if I had to guess, probably in the 1960's.
The battery is 4 1/2" x 4 1/2" x 6". It weighs 11 pounds. So, it will be a bit costly to ship.Not sure if it would charge by adding the correct electrolyte solution, but most likely would. This battery is more for "display" than "use".
