Thanks for posting. That is a very pretty thing. I like.
I'm tempted to have a play with fire pistons. The all brass units look a good place to start, but seem a little too industrial for my liking. Looking at that one I suppose I could play in brass and add a turned wood sleeve if I get on with it.
My rubbish eyes are telling me that it has a rubber O ring as the seal, along with a little bag of spares, correct? For the benefit of a fire piston novice what is that on the lanyard? Looks like a tool of some sort.
