Holy shit! Just as I get all excited about Dan's antique flashlight, I follow a link from his site leading to the "Flashlight Museum," a trove of amazing retro models showcased by a flashlight aficionado. Above, the "Rod-D-Lite," a combination fishing rod (or handle and reel, at least) and USALite flashlight, made sometime in the '40s. Fantastic.
And here to the right, a Sterling silver flashlight-shaped flask from the Prohibition era.
These are both just from the "Recent Acquisitions" page! There are literally dozens of noteworthy flashlights in his archive. Go check it out.
