They made PG 1894s for one year in 357,41,44,and 45 caliber. And darned few of each caliber. To convert you need a tang and a lever, the butt stock is not caliber specific and fits any PG Marlin from the 39A on up. Good luck ever finding a tang, I worked in a Marlin service center for a decade and never was able to get my hands on any
