A tiny little blowtorch that seems to have been meant for tasks like jewelry making, this is an alcohol-burning torch made in Germany for the Van Praag Sales Corp out of New York. Estimated date to be pre-WWII, judging by the brass construction and the fact that it's an imported German product. You might be able to get it working again- there's still cotton inside for soaking up the fuel, you'll just need a flint strike to light the fumes.
