Hey guys, I was hunting the old homestead the other day and found this lid of some sort I guess. I have tried researching it online with no success and was hoping someone on here could enlighten me a little on what it is and what

the initials represent. The initials FF are on the top.

Not a clue...............

Does it screw on or does it look like a lid. Kind of looks like a pipe cover that fire fighters used to gain access to water main at a building or factory. But not 100 percent sure.

It has two threads so it screws on, but to what I have no clue lol the homestead I hunt produces things from late 1800's to early 1900's real turn of the century.

Looks like it may have been made to re-close under pressure, from the two side "pinches" where a flat tool could be inserted on edge to tighten it down. Very interesting find!

Thanks, I thought it would be pretty easy to figure out, but this one is actually stumping me lol

For some reason I recall having something like this before. I believe the grove on the top is for a wire clip to hold it down sort of like the ones on a glass top of a mason jar. I would think that would mean it was to be used in a pressured item. Maybe some sort of cap to a radiator?

I' m thinking radiator cap. Fairly early. Nice recovery.

mreese1849 · Mar 23, 2013

that was one of my thought as well, but radiator cap for what? lol

I think I got it. It could be a lid for a keg.

I have no idea lol thats a good guess. Hopefully one day someone will run across a picture of one or find out what ff means. Slim chance for that to happen, but it would be cool just to know what exactly it came off of.

If you post things like this in the whatsit section it may get Id'ed,quicker........I beleive that is a lead cap from a large black powder can :thumbsup:

I cant find an exact image right now,but I have seen them....any way "FF",is actually a grade/type of Blackpowder.The "teats",were to tighten the cap,and they were made of lead to prevent sparks

it would be for the large keg type

My thoughts concur with Kuger, regarding this recovered item. :icon_thumright:

I believe this is a lead or lead alloy (non sparking) threaded cap for a large size gunpowder can or keg.

FFg (grain) is in fact a double fine grade powder:
By the late 19th century, manufacturing focused on standard grades of black powder from Fg used in large bore rifles and shotguns, through FFg (medium and smallbore arms such as muskets and fusils), FFFg (smallbore rifles and pistols), and FFFFg (extreme small bore, short pistols and most commonly for priming flintlocks). A coarser grade for use in military artillery blanks was designated A-1. These grades were sorted on a system of screens with oversize retained on a mesh of 6 wires per inch, A-1 retained on 10 wires per inch, Fg retained on 14, FFg on 24, FFFg on 46, and FFFFg on 60. Fines designated FFFFFg were usually reprocessed to minimize explosive dust hazards.

The link below and discussion covers similar large size powder can caps.
