How old is my Barbour solway zipper

[Iancowy]

Got dads old solway and cleaned it up and it looks great but not sure has how old it is. It has aero zip with large ring pull, newey press studs and goldish coloured label. Help

Barbour sold that model unchanged for decades, so you could probably get a better idea of age by figuring out hold old your dad is (was?) and guessing when he might have bought it.
