SOLD SOLD Conversion cylinder

[reno]

The cylinder is sold, thanks for the help. I have this conversion cylinder I'am going  to sell that looks unused or fired, and I know about what they sell for, but I don't know exactly what caliber, who made it, although I know Howell makes most of them, or what revolver it goes to, I think to a 1858 Rem. I measured the cambers at .450/.451  a 45LC will go in perfect.
Thanks again,
Reno

The cylinder pictured is for a Remington.  With the short chamber, it's chambered for 45 Schofield.  I don't know what manufacture of gun it's for without actually dropping it in a gun.  It has been around for a while though.  New Manufacture Howell cylinders don't have the safety notch between the chambers.

Thanks again Coffinmaker, just wanted to know before I put it up for sale. You and others on this site know a lot about these a I have never had one. I have many Conversions, but none that were converted from original black power revolvers.
Thank Coffinmaker,
Reno

I also think the cylinder is for a Remington NM 1863 Army Percussion Revolver replica.
My 5 ?-cents and if memory serves: the .45 cal. drop-in cylinders have 5 chambers only but the .44 cal. ones have six.

OOPS      Perhaps I miss-read your original question.  I was of the impression you had tried a 45 Colt cartridge and it was a no-go.  You didn't indicate you had a bunch of case above the cylinder breach.  With your dimensions, that left 45 Schofield.

If 45 Schofield also doesn't fit, and if there is NO chamber throat, it "may" have been made for 44 Colt with heal base 451 bullets.  If that, it's a very limited market.

Kenny Howell did make Remington cylinders for 6 rounds of 45 Colt.  The chambers were bored on an angle to the barrel axis to allow for six case rims.  Curious solution but it worked rather well.

reno,

The Ken Howell, or R&D made drop-in cylinders will have letters stamped on the rear plate.
These will be something like this... R & D M for (Armi San Marco) or R & D U for (Uberti) and so on with the 4 different major Italian manufactures. I think Taylor's & Co. did the same thing, but am not sure.
The letters will help to identify the Italian maker that cylinder was to fit. Does your cylinder have any such lettering?
Hope this helps?
My best,

Blair, it has letters RD&U on the back of the cylinder.
Thanks

reno,

Then this is a Remington style drop-in cylinder made to fit Uberti NM '63 revolvers!
My best,

reno,

Mine were all .45 Colt 6 shot plus one Rodgers & Spencer.
I would suspect yours maybe .44 Colt? It all depends on what part, and how much of your .45 colt case does not fit, and if it were full length sized before you tried it.
My best,

reno,

 The breech plate should be flush with the main body of the cylinder when loaded with the proper case and primers.
The .44 Colt rim dia. had a quite small OD. They were made this way because the cylinder pins were rather large in dia. and this didn't allow for a lot of room, especially in the 1860 Colts with the rebated cylinders.
I hope this helps.
My best,
 Blair

The box label not withstanding, those appear to be 45 Schofield cases.  The Schofield rim is larger than a 45 Colt Rim.  The rim diameter of the cartridges shown are too large for the recess in the cylinder.  The 44 cases shown are a tad undersize.  Neither is correct for that cylinder.

Could it have crud keeping the .45 colt from seat correctly?

Perhaps it is time for a chamber cast?
If you don,t have cerrosafe, you can try hard wax like sealing wax for a rough idea...

Merry Christmas one and all

Coffinmaker, you are right as always, I tried a 45 Long Colt and it fit prefect.
Thanks again to all. And to you Coffinmaker,

Hello reno,

Here is a picture of my 44 Cylinder with a 44 Colt & a 45 Colt cartridge.
Mine is also marked 44 & P on the rear side of cylinder, with a P on underside of cap.
I purchased directly from Howell for my Pietta.

Hope this helps, AntiqueSledMan.

Almost forgot, I also have a 45 Conversion Cylinder for the 1860 Colt.
Attached are a couple shots showing Cylinder stamped P
with a 45 & 44 Colt cartridge, and the Cap with P3 stamp.
