An interesting original conversion cylinder

[Riot Earp]

Anybody seen one like this before? Six firing pins and a gate!

That is one heck of a piece of craftsmanship!  Nice photos.  Thanks fer the post.

WoW. . . . someone did some nice work long ago.

[Leo Tanner]

If I had 1500 layin around I just might make a bid...but I don't.  That's one special piece.

[Bull Schmitt]

If the back plate is "locked to" the cylinder like the R&D version, what purpose does the "loading gate" serve since it would rotate with the cylinder? Am I missing something?

[Qball]

On the left side on the recoilsheald there is a "button" to lock the backplate in loading position
and on the loading gate there is the lock pin for the cylinder to folow the backplate.
When opening the gate the lockpin relese the cylinder to spin free
Hope you understand my try to explane

I had the same question as Bull, but yeah that explains it. That is incredible. It almost seems too innovative for the 19th Century.

[Qball]

Yea.. some one did some thinking there.
Very impressive

[Raider2000]

I had to studdy it for a bit & WOW what craftsmanship & a lot of thought, I'm not sure if my nogin would figure this one out.

Ah My Dear Monsieur Earp -
The 19th Century and those dandy Victorian chaps were the Acme of gadgetry and mechanical wizardry. Just peruse  the inner workings of a common pocketwatch, let alone a fancy, jeweled movement that sounded the time audibly . That was also the time of the early mechanical computers, and great strides in  Newtonian Telescopes, all of which were constructed by skilled hand labor.

Here is fine example of a precision astronomical instrument from 1851

Did you know they were capable of measuring events to a resolution of  one millionth part of a second ?
In fact I will post here an excerpt as posted by our esteemed colleague Rawdog over  here http://www.theopenrange.net/forum/index.php?topic=6199.0

-------------------
I thought you might enjoy this passage from Captain Ingalls' US Army Artillery Textbook of 1894 and referring to
Noble and Abel's experiments of 1874 and a little later:

Noble's Chronoscope.
The almost infinitesimal intervals of time required for the second method are determined by means
of a chronoscope invented by/ Captain Noble which is thus described: 2 "In its most recent form it consists of a series of thin
discs each 36 inches in circumference, keyed to a shaft which is made to rotate at a very high and uniform velocity, through a
train of wheels propelled by a heavy descending weight. The speed with which the circumference of the discs travels is usually
about 1200 inches per second; an inch, therefore, represents the i2ooth part of a second; and as by means of a vernier we are
able to divide the inch into 1000 parts, the instrument is capable of recording less than the one millionth part of a second. The
recise rate of the discs is ascertained through an intermediate shaft which by means of a relay, registers its revolutions on a
subsidiary chronoscope (each revolution of the shaft corresponding to 200 revolutions of the discs), upon which subsidiary chronoscope
a chronometer, also by means of a relay, registers seconds. "

"The recording arrangement is as follows:
Each disc is furnished with an induction coil, the primary wire from which is conveyed to any point in the gun where we may wish to record
the instant at which the shot passes. There is at each such point a special contrivance by which the shot in passing .severs the
primary wire, thereby causing a discharge from the secondary, which is connected with the discharger. The spark records itself
on the disc by means of paper specially prepared to receive it. When the instrument is in good working order the probable instrumental
error of a single observation does not exceed from two to three millionths of a second."

The data employed by Noble and Abel in their discussion of the phenomena attending the combustion of gunpowder in cannon
were chiefly derived from the experiments carried on by the "Committee of Explosives" whose president was Colonel Younghusband,
F. R. S., using the Noble chronoscope above described. Two series of experiments were made by the committee with the
10-inch 18-ton gun the results of which will be discussed in Chapter IV.

I hear ya.

I'm just not used to seeing that ingenuity applied to revolvers.

[Leo Tanner]

With all that was put in to it, the price wasn't bad.  I hope who ever got it appreciates what he has.

[Qball]

Not sold?
Reserv price not met

[1860]

Take a look at the last guy to bid on it, check out what he has been buying and how much he has been paying...Nice stuff and very deep pockets ...

60

[Galloway]

What cartridge would that gun be chamberd for?

[Raider2000]

What cartridge would that gun be chamberd for?

I would imagine that since it is 6 shot that it'd be chambered in .44 Colt or .44 Remington.
.46 Remington Rim fire would only be a 5 shot because of the rim size would prevent a 6th loading.
