WINCHESTER REPEATING ARMS Co.
WRA-0
HISTORY
The modern Winchester Repeating Arms Co. can trace its roots back to the Volcanic Repeating Arms Company, which produced the Volcanic rifles and pistols during the early part of the 1850's. When this firm was failing, Oliver F. Winchester,
as an investor, helped form the New Haven Arms Company. They were to continue the manufacture of rifles using some of the ideas of the Volcanic designs. The Volcanic rifles used .31 and .36 caliber self contained cartridges which lacked power. In June 1858, the new company took over the former premises of the Volcanic Repeating Arms Co. with O.F. Winchester as the president and B. Tyler Henry as the shop supervisor . At first sales were no better than with the prior designs and company. Then Mr. Henry redesigned the Volcanic action to handle the larger caliber .44 rimfire cartridge. To honor Henry for his work, all Winchester rimfire cartridges carry an "H" headstamp even today and the first products of the New Haven Arms Co. were
called the "Henry Rifles"
It is not known when the impressed "H" replaced the raised "H", but probably sometime in the early 1880's.
I'm putting this in there because your casing has a double firing pin strick wich also help on IDing the gun
Copied from a post on another forum
my money is on--- henry 38 - 40 -- the fact its 38 cal -its a rimfire and has dual strike firing pin marks -- henry 38 - 40 black powder type catridge * all the way. -- most likely fired from henry model 1866 rifle (38-40)
the 44 cal henry repeaters used during the civil war by union troops -- the casings found at battle sites have that same exact rimfire type casings but in 44 cal with dual strike firing pin markings ,
