Unidentified Hults Bruk Agdor Axe

I recently acquire in a fleas market for a ridiculous price ($5CAD) an axe or hatchet head (no handle)that seem to be quite old from your brand. It’s all rusted and in not a such good conditions but I will restore it. I’d like to know if you first can tell me how old it can be (manufacturing in which period) and what is the best handle size for it. On the left side there are the engraving:

1-a circle with HB inside and beside another one with an H
2-just below AGDOR
3-below HULTS BRUKSAB
4-MADE IN SWEDEN

It weight 875 grams but because the wear it may have been more we clearly see bad sharpening
grooves. The cutting edge is about 8.3cm the full length is 14.5cm the thicker point as 2.8cm. If you have an email I can send you pictures of it. Any informations regarding that nice piece would be deeply appreciated because I will restore it use it for my bushcraft activities.
