This is Finland, where they were made... I went to the military depot shop in Hämeenlinna. They're selling all the green or OD waffles made by Exel as the Army has adopted the black, yet stiffer version as standard issue. I got eight waffles of which only two needed a bit of tuning to work properly: the newest versions with the lanyard loops and square takedown buttons seem stiffest.
They're also selling older, well used Sako/Valmet steel mags... but as I could notice, you'll get a decent one only with luck. They're all pretty beat up. Then they've got lots of Suomi MG drums and Sten box mags... and an endless supply of Mosin parts and furniture.
