Guitar Serial Number help

im wondering about a guitar I’ve had since I was 8, my dad gave it to me it was his before that, im curious about its age currently.
All I know is that its a Hohner dreadnought acoustic model no HW 220, and the serial number is partly blocked by the truss rod but I was able to make this much out “3(I think its 01 after that but its blocked)4102443” does anyone have any information?
