Have now established a source of electrolyte, Sodium Hydroxide.
There were two electrolytes used in mercury batteries, Potassium Hydroxide and Sodium Hydroxide. The latter preferred for heavier current surge applications and elevated temperatures.
Now need to find some thin zinc sheet, zinc oxide, and should be ready to make one.
Possibly the zinc sheet can come from an old dry battery casing, the zinc oxide is used a lot in skin cosmetics.
Nearly there!
