Marlin Model 1889 was manufactured from 1889 to 1894 (a few hundred were put together from parts up to about 1903.
Marlins first and maybe the first side eject lever action rifle.
It was chambered in 44-40, 38-40 and 32-20 (a very few were chambered 25-20).
In 1894 it was replaced by the Marlin Model 1894 with a few improvements.
About 55,000 were made. about 18K of those in 38-40.
Proper barrel markings should be Marlin Fire Arms Co., New-Haven, CT. U.S.A. Pat'd Oct. 11, 1887, April 2, 1889.
A beutiful gun, I own a 44-40 myself and would like to own more
Hope this helps.
