Brass Plunger

[WilliVanilli]

Found this today detecting a creek near an early colonial homesite. At first, thought it was a vintage bike pump. Then thought it was a early syringe. Now going with grease gun. Plunger still slides and works with compression. Tip was clogged but after poking through, some greyish stuff came out. Stamped “JS” on top of the rim. Any help would be appreciated. Thanks!

By the way, JS could be the military inspector that approved the purchase.

Her test could also determine the presence of hydrocarbons, yes?

I’m sure they could test for the presence of most anything. Where are you going with this theory? I’m intrigued.
