There are few good quality bench vises without the maker's name cast into them. The Wilton with the Snap-on decal is the only one which comes to mind.
Having said that, the first photo is so blurry, it's useless. Impossible to guess what might or might not be there.
Bottom line - there are enough Chicom bullet knock-offs one should be wary of what it doesn't say.
