I bought this today at a Militaria show.It's missing the lever and pull pin, but looks like everything else is present.I didn't know the igniter pin was with it until I got home and removed the fuse.When I turned it over the pin fell out.A previous owner must have put it in there to keep from loosing it.I don't see any markings on the body.Maybe when I clean it up some,I may find some.There is a small marking on the top of the fuse,but I can't tell what it is.On the fuse body it's marked J1 and then 37.The iron plug in the bottom looks to have been staked in place after it was installed.Anybody know if the lever handles are available?
