Oops -- I didn't get to usenet last night -- too much time
fighting with a drafting program for a project I'm building. :-
So -- I'd better post my opinions before I read anyone else's.
Posting from rec.crafts.metalworking as always.
2563) My guess here is that they are metallurgical samples for
analysis by some process or other -- microscopic or other.
The sample is cast in the epoxy (I think rather than Bakelite),
identification is scratched into one end of the cylinder, and
the other is machined and then polished to expose the metal
samples for study. Not sure whether it is simply sanded or
lapped to provide the needed surface finish. It looks as though
most of the samples were extrusions, so I suspect that grain
structure was being examined using perhaps a phase contrast
2564) Given the U-bend in each of the cross pieces, I suspect that
this was a support for either a flexible pipe or for electrical
cables. This sort of thing (usually metal) is typically used in
the between the floors spaces in multi-story buildings. (The
ones which I have experienced are not quite tall enough to allow
walking upright even without all the pipes, cables, air
conditioning ducts and such which crowd the space
Not sure why this one is made mostly of wood, and why in the
middle of a more gentile environment. :-)
2565) Perhaps the handle for a beer dispensing tap. The large end
(which we don't see end on) would hold a medallion to identify
the beer and the brewery.
2566) Looks to me like something for smoothing concrete.
2567) Perhaps something for analyzing the purity of the ore mined?
Not sure why the crown spikes.
2568) I think that this is a handle (key) for turning on and off power
using a switch with a recessed actuator to prevent the general
public from switching things on and off.
O.K. Now to stop and send this before I go on to read the
now exposed answers.
