AFAIK these were commercial builds in the Italian Tipo 2 Garand configuration using surplus Danish Beretta/Breda receivers and surplus Italian military Tipo 2 parts, including an op rod, rear handgd, 7.62mm barrel and stock, all of which were shortened .5 inch from the standard M1 Garand parts. You can also use the Italian military surplus 7.62 spacer block which prevents attempting to load an en bloc clip with standard .30-06 ammo. All other parts are standard M1 Garand parts. To the best of my knowledge the Danish military never adopted Garands chambered for 7.62 NATO.
These make up into nice rifles and all of the Italian 7.62 barrels that I have used gauged near new in terms of muzzle and throat wear.
