What year is this front rim off of?

[Subtle Focus]

I have a 1979 Yamaha xs400 and it has mis-matching rims on the front and rear, below is a picture of my front rim (sorry if the rough paint job and lighting make it hard to see the best I can do in my garage) would anybody have any idea roughly what year that rim is from. Its drum and I am looking to replace the brakes as it is needed and I dont want to order the wrong parts when I go to the dealership or order them online.

Tell them its an '81 XS400 Special II w/18" spoke front wheel and you will get the right parts

My 79 has the same rim and it is what came with it.
