Hi new to the forum. I was wondering where I could get info on three 336 Marlin Rifles I inherited? The serial numbers are 25039XXX 0802XXX and AD58XXX. I notice The 25 is eight digits long where the other two are seven and one has alpha digits and the other two do not. The 25 number was on top behind the hammer the other two underside at the lever ring. Any help would be appreciated.
