Lead cap of some kind??

[sandsifter66]

This is a 2" diameter cap of some kind roughly 3/8" thick. Made of lead. with rings around it. Stamped FFF on top. It was attached to something iron because it has iron in the groves. Looks like a slot on top to twist off something. Small inside hole 1 1/8" diameter. Larger hole 1-3/8". Found at old home site or loading place . Let me know if you know what it is.
Thanks

thinking lid to a black powder flask or container with the 3 f's possibly meaning pistol powder.

3- F's would be the fineness of the powder. I was thinking the same thing, cap from can of powder...NGE

Yep,off of a large powder can....what the powder came in to fill the flask We seem to dig them in mostly the 1870 is sites

I looked up some info on it and found one that had a wire loop around the top ring, then twisted and attached to a small chain that hooked to the can. I was hunting in a place that goes back to the 1840's. I knew it didn't come off a flask. too big. It said blasting powder or pistol powder. I guess since it had no threads it was pressed on and would not create a spark because of the lead. The FFF is the fineness of the powder. Some people use FFF in black powder guns now. The more letters the finer.
I had not time frame so thanks. The 1870's is ok with me.

Very interesting fact is,due to the fact it is press in and a type I have not seen an exact match,it may be earlier?The earlier EI Duponts were press in

Actually I believe it is threaded, and what we are looking at is both the cap and the spout ring that was attached to the tin can.

Usually we are accustomed to seeing the larger powder cans in Western American context only after the 1860's, as Kuger has shared, when drift mining and hardrock shaft blasting became more common place. With Eastern American sites though, time-frames could be different.

Here is a great reference book on early powder cans and tin containers:

This 25lb can looks like the ring would fit the clips on the top of this can, Maybe.
