Spencer Reating Rifle feels a bit powerful.

[Kitfux]

"Spencer’s first model was believed to have been completed in 1859. His friend R.S. Lawrence, of the firm of Robbins and Lawrence were early contractors of Sharps rifles and carbines. So it is not surprising that some lock parts with interchange with the Sharps. Spencer’s first arms were in .36 and .44 rimfire. These used a smaller frame than the later military models. Spencer obtained his first patent on March 6, 1860. A second patent issued July 29, 1862 contained several improvements to the original design."

That's as far as I got myself, but this:

"While these are the two common calibers of Spencer firearms, other chamberings exist. A few very rare and valuable sporting rifles were produced just after the Civil War, mostly from condemned parts.  The greater number of these used a bottlenecked 44 caliber cartridge based on the 56-52 case.  There are also a very few early prototypes in various small caliber chamberings, particularly 38 and 46 straight."

seems to refer to yet another batch, or is it referring to the same models as the first article 
"Early prototype" would indicate something like single digit numbers, wouldn't it?

Another weird, but moderately popular repeater (>1000 production number)

Looks interesting. What are its calibre and capacity?

French Guycot Chain Rifle, 80 rounds of centerfire cartridges

"Manufactured circa 1878, this unusual and rare rifle features a chain housed in the frame and stock which holds 80 rounds of centerfire cartridges. The "endless chain" has carrying cups that hold the rounds. Once loaded the rifle can be fired as fast as the trigger can be pulled. The belt is revolved until a chamber (or cup) faces the barrel. At the same time a long firing pin is retracted. An inner barrel is drawn back through the heavy outer barrel until it covers the bullet end of the cartridge. When the long drag on the trigger end, the final pressure releases the needle like firing pin, which drives through a small opening in the base of the cup detonating the cartridge primer. The rifle fires a lead conical bullet which is hollowed out to accommodate the powder"






Meigs Sliding Guard Action Repeating Carbine

"Patented by Captain Josiah Meigs in 1866, this carbine is fitted with a unique action which provided a level of firepower virtually unknown in the era, with a potential rate of fire of nearly 160 rounds per minute, as compared to the 200 rounds per minute of the Model 1861 Gatling Gun. Blade front and flip-up adjustable rear sights, with no visible makers marks. The buttstock of the arm consists of a buttplate and carved walnut cheekpiece fitted to the 50-round tube magazine, which contains a replaceable 5-track rotating frame with spacers for 10 rounds per track. These frames could be preloaded, cutting down reload times substantially. Mounted on a rail between a pair of mortised tracks is the trigger guard assembly, which has a checkered firing trigger and a smooth long release trigger, and is reciprocated back and forth to rotate the magazine frame and move the breechblock, which extends up out of the frame to eject spent cartridges, Full length forearm with raised decorative carving and cord wrap, leaf pattern raised carving on the cheekpiece and nickel finished brass buttplate."





and the "Kalthoff repeater, which was a type of repeating firearm that appeared in the seventeenth century and remained unmatched in its fire rate until the mid-nineteenth century. As its inventor is unknown, it is named after a family of gunsmiths that has come to be associated with the design. The Kalthoff had two magazines, one for powder and one for balls (some had a third for priming powder)."

in the Louis L'Amour novel Jubal Sackett, Jubal has a pair of pistols that can fire 12 times without reloading.  to reload you point the barrel at the ground and move a lever.  can't remember the name of the pistols, but if you're interested you can probably find a copy at Barnes & Noble, or at your local library.
