I know if I call Marlin they would send a manual.
Have read on other forums that there is a minimum and maximum warning concerning the 1894c only, but nobody gave the details.
Happened to luck up on finding a used version. Made up for me losing out on a 42 year model Winchester in 32ws the other day. Was out pawnshopping, ran across the Winny in about 85% condition for $250, but wanted to think about it some. Went back the next day to get it, and it was gone. Teaches me not to go pawnshopping without money in my pocket.
As for prices on new Marlins, three different dealers locally has quoted me from $390-$399. One dealer had two in stock, the other two dealers would order it.
