A lot of the time there is a SA in a box on the receiver. Yours doesn't appear to have one. I am just basing it off of the front sight and the fact that it has a import marking. I didn't see anything else tell-tale which says its Finnish, I just am not seeing anything that is tell-tale for it being a SCW rifle. So to me that makes it a Finnish rifle.
Sanded stocks are common on both Finnish or SCW rifles.
