leftmost - Phillips NF 09627 2A. -- presumably a fuse, 0.195 diameter, 0.51 long - I can find the part number listed as a militiary aviation part number - what do these fit? what uses this odd type of fuse?

pile of rectangular objects - labled A1, A2, B1, B2 and so on thorugh D2 - label seems to specify which hole has the pin in it - 0.820X0.5X0.5 inches, they clamp to something with the screw, presumably the pins trip switches or pawls for some automation purpose?

old mystery thing with a brush and a blade - brush is 0.2 inches in diameter, base is aprox .75X1 inch, blade is hard steel, 0.520 square with a hole in the center, extends through middle of base - all I can think of is that it might be used for cleaning up slots between commutator segments on a big motor or generator. blade is 0.045 wide.
