Looks like a Meyer blade to me, a pretty beat up one at that. I suspect it was used to move a lot more then just snow.

I have a pair of those goofy plow lights around here somewhere from my old plow. My son's wife stuck their Chrysler 300 in a ditch a few years ago. So they could keep driving it while they waited for the nose piece to come in, he grafted one of those headlights onto their 2000 something Chrysler 300. I believe it was his idea of punishment for her driving 70 mph in a snow storm, she drove the car with that headlight for a couple of weeks. That took the goofy headlight deal to a whole new level! It did however get both jobs done, transportation and punishment. LOL! Gene
