Finally getting back to this after being away and/or busy for a few
weeks....

1387 -- Very strange cast object. Possibly used in a metal casting
operation? Molten lead or whatever could be scooped (or melted) in the
ladle portion, and scum and slag captured in the hollow cylindrical
hinged portion by tilting the works slightly, then the purer metal
poured into the mold.

1388 -- Googling "Brains and Pictures" reveals that it's an austrian
firm specializing in camera handling machinery for television and motion
picture use. It would therefore seem that this is some sort of a
motorized camera positioning system.

1389 -- Clearly a multiple saw of some manner, seemingly used to saw
grooves in or possibly strips of a sheet good of some sort. From the
substantial size of the arbor, I'm guessing maybe its used for metal
(Aluminum?). The sizes of the strips or groove spacing obviously vary;
it's not clear, to say the least, what possible construction they may be
used in.

1390 -- Spring compressor, maybe for valve springs on old engines?

1391 -- Early form of GPS navigator device, giving directions to the
operator of a motor vehicle. Maybe used by drivers on a bus line.
"Macadam and pike" would refer to paved roads or toll (turnpike) roads,
presumably the smoothest, fastest, and best-maintained of the day.

1392 -- Clueless, but with a nagging suspicion I should recognize this.
The cutout appears to be a bottle cap lifter shape, while the toothed
bit looks like it should engage a bit of belting, two functions that
generally don't go together.
