Your Levermatic may not have a serial number! Pre 1968 .22 rifles were not required to have a serial number, and are legal without one. There may be a date code on the left side of the barrel, near the chamber area. The date code will be two letters, a thru L for the months Jan-Dec., and F thru L for the years 1962-1968.
46M was made 1940-45
