there is a Marlin 1881 combo loading tool that went on E-bay in the last couple days and I was trying to see if anyone has any information on them. Did Marlin make them or were they made by some other company (Ideal)? The guy lists a ser.# on it. Was it part of a package with a rifle and was that also the ser.# of the gun? In what time period were thet made? Thanks.
