I have one the same vintage. Blued bolt model.
Have you taken the bolt end off? If you haven't just twist the bolt face end and it will come off. No springs will assault you but as always you should wear safety glasses. There is a small detent arrangement so watch for that. You will then see how to remove the firing pin. Check condition of tip and cleanliness of the firing pin hole thru the bolt face. Check how well the firing pin engages with the slotted shaft from the main spring. Check for any excess wear (unlikely they should last forever). Check cleanliness overall.
I always uncock my bolt between uses (maybe a couple of years apart). It takes quite a bit of handforce to recock. Decock yours and recock. If it is real easy to recock by hand the main spring may be getting weak.
Check that the recesses in the barrel where the two extractor claws go into are clean although this shouldn't give you the issue.
