Not sure of the prices for one of these over where you live.
I paid $950 NZ for mine.
The stamp on the barrel-- Blackpowder Only
I have this. They are what is called B grade rifles made after 1900, mine has it and was made in 1906
Marlin had a number of barrels left over from the black powder days and made these rifles up with them.
The steel is good quality but not up to the pressure levels put out by modern powder.
My rifle is in 32-40 and i shoot it with BP. Its really addictive.
Hope this has helped a little
