Look on top of the reciever. It should have the Swedish crest, manufacturer, and year. Check to see if the numbers on all the parts match. The more matching numbers the better, kinda like playing the lotto
I think tator134 is right about the left one being a 93 action. Possbily a Spanish?
If you could get pics of the top of the recieivers, specifically any crest, we could probably ID it.
