lot tiny oil lamps, ship's lantern pivot wall sconces, copper plate metal

Lot of tiny vintage oil lamps, all metal, nearly all made ship's lamp style, to tilt for table use or wall. Most of these are marked Hong Kong, so are 1950s or 60s vintage, we think? The plain (non-pivoting) lamp measures 4 1/2" tall.

These look a little rough, with some rust spotting, and many without glass chimney shades. I don't believe any of these leak, however, so they might be fine for use? We think they'd be terrific blanks for decorative tole painting!
