Tiny Tuesday - Metal

I went to a girlfriend's for lunch and to play Canasta. It was beautiful weather so we sat on the balcony. We have had a 2 day respite from the rain but it is supposed to rain again tomorrow.
The TT theme is metal and I searched for something I haven't blipped before. This is some detail from a brass gunpowder flask that I acquired in Saudi Arabia. Thanks to trisharooni for hosting.
