Is the. 603″ the rim diameter or the head diameter? Head is just above the rim. Same for the .476″. Is it at the mouth of the neck diameter? Looks like the cast may have gotten into the lands?
45-70 is .480″ at the mouth of the neck. Head diameter is .505″. Rim diameter is .608″. Case length is 2.105″.

I know that you mentioned that, Bert. This makes for an interesting issue going forward with rebarreling this rifle. We don’t know anything about the barrel that is on the rifle presently. The bore looks too good to be original and it has no Winchester markings. The Cody letter gives no information about the original caliber.
It wouldn’t state the caliber unless it was something different than 45-70.

Kevin-
In my humble opinion a 43 caliber wildcat based on the 45-70, a custom barrel (among other alterations) and the absence of an indication of a non-standard chambering all fit together nicely. Maybe not what you were hoping for but my guess is you have an interesting custom version of the Hotchkiss. I’d like to see some pics before you send it off to let Mark work his magic on it.

Thanks for all your input. .47.6 mouth, .509 head and .603 rim. I knew that the rifle was worked on before. I thought that it might have been chambered for a standard cartridge…… I didn’t think about a straight wall wildcat.
I will have Mark convert the rifle back to 45-70 with a 28-inch barrel. He was going to be looking at a high condition original military rifle the other day to take notes.
What additional pictures would you like to see?
I stated I’ve never owned a Hotchkiss rifle but I am not unfamiliar with big bore bolt action tubular magazine rifles. As we know, Winchester had competitors.
In the Remington Keene line, here is a .45-70 and a .43 Spanish (the .45-70 is the carbine; the .43 Spanish has the sling swivels):
One of the interesting things in comparing the Hotchkiss to the Keene is the speed of operation. This is where Winchester has Remington beat. The Keene requires that you manually cock the hammer after each bolt cycle. Kind of odd. I would have thought it wouldn’t have been that difficult to design the action such that the hammer is cocked each time the bolt is cycled?
Thanks for sharing the pics of your Keene’s Steve. They look to be in excellent condition.
The mid to later 1800’s is a very interesting time in small arms development. My collecting interest has gravitated towards antique/ vintage bolt action hunting rifles. When I was younger, I was all about military firearms. As I have grown older, I like the sporting rifles because I can take them into the woods and use them for hunting. I get a lot of satisfaction hunting with these old girls.

Feel free to ignore my requests for additional pics, I’d forgotten about the seller’s excellent pics in the OP….unless of course something interesting turned up upon inspection. I enjoyed the old-school look of the stock, you have some tough choices to make.

I’m trying to figure out how to get/ or make a correct style butt plate for this rifle. I’ve looked at the N.C. Ordinance catalog at their reproductions. They sell a “spurred” plate for the Model 97, however, it is smaller than the stock dimensions. They also make an oversized Model 12 plate that is without a spur.
I’m wondering if I could Frankenstein the 2 plates in order to have something to make a mold. N.C. Ordinance told me that they would need an actual plate to make a mold.
Thoughts?
