Rebuilding 2 saws. Serial no look up

[smeath91]

Hey guys this is my first post. I am currently rebuilding 2 saws one of which 1 was my grandfather's 028 super av and an 024 I picked up for $50 Australian. Just wonder if anyone can give me year of manufacturer from a serial number and also on the 024 if it's any variant like a super or woodboss. Thanks in advance.
