Think it was back in mid 1960s (?) that they changed the unis to have five (5) stripes on each sleeve.
They evolved to a slight degree until the mid 1970's when they added a 'separating strip' between the five.
In 1984 they had the "G" logo actually IN the stripes on the sleeve.
But in 2000 ... they kind of went 'retro' and shrunk the size of the stripes on the sleeves.
I found a link ....
Have a good one
