Hi Ivor,


Yes...Chicago...wow, and they get all the way over thar...!

How cool...yes, (them slender walled Brass tubes) they are
very handy for many things...I like them. That would be a
fun Factory to visit, to have the Chef's Tour of...
The ones I am used to, come in graduated sizes which fit
snugly into their next size, so one may nest quite a few of
them each inside the other...like a Car's Ariel...not that I
have a reason to...

I use them for making various small furrules mostly.

One could taper-reamer or countersink their inside edge, and
have something of a Cork Drill I suppose...


I do not know their alloy, but I consider them Brass...

Do you know the name of the Alloy as is used for Ammunition
Cartridge Cases? These seem similar to me...

"Bloomfield Gilding Metal" was the original one as succeeded
Copper if memory serve, I imagine it is still the de-jur of
alloys for the task...those deep draws of the forming into
the blind lengths with a thickened end (especially as for
something like a 50-110-500 Borschart or Sharps or other)
was a tough Bill to fit when they were first after the kind
of metal as would do it...and as would also work-harden in a
convenient way for the final draw to arrive at the hardness
and spring-temper and resillience they wanted...

Copper did
not do so well sometimes in the resillience department...or
the springy department...but did pretty good in the
get-stuck-in-there department, once the breech was warmed
up.

We may recall old Gen'l Custer and his boys was supplied
with
them 'Copper' Case Berdan Primed 45-55-405 Cartridges for
their
Carbine (or was it the 50-70-450 still? hell, I forget
now...or several were concurrent anyway, depending on
requisition preferences,) ways of faith...(which Copper
Cartridge Cases, when
the breech got 'warm', would stick pretty good, and tear
when the breech ejector
caught them and leave the recalsitrant empty shell stuck
nicely in the breech, with a torn edge of the rim, for them
to try knocking out with their Ram-Rods, which did a nice
job of knocking the Case's end off, so there was then just
the vestigual cartridge 'tube' stuck in there...whilst
the operative pried at that with a pocket knive or other,
finding that Arrows enjoyed the liesure his now occupied
form presented...oh well...

And not long after, our young Mr.
Bloomfield Gilding Metal was...found in a basket on a
stoop...embraced, adopted, and raised in the tender bosom of
gratitude...)


Hmmmm...the Glycerine...good idea...



Oh silly me...
