Alpine mounts are rare. The one I have was about the same condition before restoration with desert tan paint with the red primer. Yours looks to be excellent condition and a very fair price.
Is the caliber 7.62X51? If so, the jaws of the MG42 links need to be opened up. The 7.62 case is a larger diameter than 8MM. I used small needle nose pliars to force the link jaws slightly wider by using reverse pressure on the pliar grips with the needle noses inside the opening of the link. I did this for my MG-42 since I only shoot 7.62. Hope this helps.
