If you don't know about Valmet it's not surprising. It is a rare version of AK from Finland. One of the first AK imports into US back, back, back in the day. What's even more rare than Valmet is its' bayonet. Really distinct and unusual style made by Fiskars and now even if you can find one it'll cost you more than most budget to mid-tier rifles.
hence my attempt at making one on my own with a bit of a flair too.
