Front wheel, right? Basically the same procedure as most any make of car from the 20s thru the 80s or later. No puller needed, just remove the grease and dust retainer cap (it unscrews, use a plumber's strap wrench) and then just lift out the outer wheel bearing retainer nuts, lock ring and outer bearing with your fingers, and take the drum off.
It's the rear drums you need a puller for.
See picture of removal of the grease retainer cap with a strap wrench and picture of front brake (same as yours):
