It has been in my family for many years but my grandfather passed away 40 years ago without telling any of us the story behind it.
I thought it was from Finland around 1903 but the K.S. makers mark does not match up with that from what I can tell.
The identifying marks on the back are K.S., then a crown, then 813H, then an A with a line across the top and a dot on top of that and finally an X4.
Any help you could give me would be greatly appreciated.
