I'll include this in my other thread, but FYI (if you've bought one)...
When my Lahti M-40 bolt was disassembled for refinishing it was found that the firing pin spring [14] was broken into two pieces.
It still functioned (I shot it dozens of times) but it is still something that I think should be removed & examined.
The firing pin and spring are both held in place by a pin [13] which needs to be driven out to clean & inspect the firing pin/spring.
Pic attached.
