Hults Bruk – 1.25 lb. Hatchet Pattern – Pre 1988

Recently my father-in-law gave me this old hatchet that he found on his property. Not knowing the mark, he gave it to me knowing I would put it to good use. I haven’t done anything with it yet, but I am curious as to the era it was made. It has the circled HB logo and weighs 1 1/4 lbs. Anyone able to help identify?
