3139) Interesting. In part it looks like a whistle, including the
fipple formed half by the wood and half by the end of slot.
But -- if it were a musical whistle, it would have larger holes
on the side, and with variable spacing and sizes to tune them to
And the perforated cone would not be there at all.
Perhaps it could be a whistle which is powered by a vacuum drawn
through the perforated cone.
The shape of the fipple appears wrong for it to be powered by
steam fed in through the perforated cone. You only show one
view of this, and I suspect that there is a hole though the wood
just behind the fipple.
3140) Strange. All formed from a single piece of wire.
At a guess the duck-bill to the right fits into a tube, and it
supports a tubing (glass or rubber) in the other two. Perhaps
used in a chem lab.
Maybe it could hold a test tube on the end of a distillation
condenser for sampling before the final product goes to a larger
3141) That is the most decorated Acorn cap nut I have ever seen.
Unlikely to be a commercial product, though it might have
started life as a normal Acorn cap nut.
And the size is rather large for most acorn nuts.
3142) A pipe reamer. Used for removing burrs from the inside of a
just cut length of pipe.
Used in an old style brace from the "Brace and Bit" days,
BTW The "large photos" site seems to have the two views of the
acorn nut and the pipe reamer interleaved for whatever reason. :-)
3143) Two normally hand-held counters. Likely used at the admissions
gate to count two different classes of entrants -- say Men vs
Women or adults vs kids.
3144) I think that this is a tool used by a blacksmith for punching
a hole through sheet metal of whatever thickness. Heat it red
I think that the two parts separate, but they might work
assembled into the hardy hole of an anvil.
Now to post this and then see what others have suggested.
You're right about it being for larger saws, I think it was for crosscut saws
that were used on trees, as you mentioned. The actual size of this saw set is 3-
1/4", I had incorrectly marked it as 2-1/2". I posted this tool a long time ago
and didn't have an answer for it until Leon sent me some information on it.
It is what sawyers call an upset swage or hammer swage.
It is a variation on the swages used for circular saws
In this image the top two are for circular saws and the bottom one
is for crosscut.
A "saw set" OTOH is used to bend saw teeth. Usually every other tooth
is bent in the opposite direction this is done to create kerf clearance.
A upset swage is a forging tool that forms the tooth metal back to
its original shape by hammer blows. There are also lever type swages
where one uses a hand crank to shape the tooth.
Here is a good explanation for swaging a circular rip saw.
