Based on the serial number format Husqvarna used before 1999, your model 36 with s/n 5213372 was likely manufactured in 1995, during the 21st week of that year. The first digit typically indicates the last digit of the year and the next two digits represent the production week. Since the model 36 was produced in the early to mid 90s, 1995 lines up with the known production window.
Has the saw been modified or rebuilt at any point? That could affect the accuracy of the serial tag if parts were swapped.
