Depends on original condition, original grips?, also which variation.
That's a Type II 3rd Model, there's 6 variations can only be determined by a picture of the top of the barrel.
No, unless it's a frame with barrels that can be changed to suit different caliber ammunition.
270 is a caliber not a model... For date check the Remington Society of America site for the date barrels codes: http://remingtonsociety.com/rsa/questions/barrelcodes

Original flint or purcussion pistols by Henry Deringer could be anywhere from 28 to 50 caliber. Remington Arms made several different "Derringer" pistols (note the difference in spelling) ranging from 17 to 41 caliber. The most widely recognized Remington derringer is the over/under double barrelled Elliot's patent chambered for 41 rimfire cartridges. Modern copies of these are readily available today in 22, 38, and 45 caliber. Dozens (hundreds?) of other small, easily concealed, pistols and revolvers have also been called Deringer/Derringer/Daringer, etc, by most people even if not by their manufacturer.

44 caliber derringer pistol.
The caliber of a Philadelphia derringer with Jukar 054167 Jukar stamped on the barrel is not known. There isn't enough information to determine what the caliber would be. A gun collector would be a good person to ask.
Remington did not make a carbine in .44 Magnum caliber. They did chamber the Model 788 rifle in that caliber. Do you have a Ruger carbine in .44 Remington Magnum, or perhaps a Marlin in that caliber? sales@countrygunsmith.net
