While I've dug some nice basic flasks, I picked these flasks at a yard sale. The first clear one looks the part, old that is, while the second blue one to me must be a repo., but still a very attractive bottle. I have not had any luck finding information, I've come across similar blue repo. flasks, but not exactly like this one. The clear / flint-like one has me completely stumped. Anyone that could provide some feedback, age, origin, etc. would be appreciated.
