Use the camera icon to insert selected photos from your album. No worries about forgetting how. (Was about 4 or 5 forgets before I got it to stick!)
Vices look to be versions of the common Far Eastern imported ones intended for use on drill presses. Numerous very similar versions came in over the last 40 – 50 odd years from dozens of firms ranging from well known names like Machine Mart to ephemeral mail order outfits that maybe sold a large box or two.
Yours look to be among the better made ones of the breed. Regrettably quality ranged almost randomly from quite decent to almost doorstop.
The tilting one is the best example I've seen. The removable base is unusual and overall it has an air of low end industrial quality.
As is well known most of this affordable imported equipment was inspired by (aka copied from) Western equipment, state sponsored in the Chinese case with drawings issued to numerous producers.
That tilting vice looks good enough to have been a Western original from which the copy was taken but, so far as I know, no Western firm offered that style. As I recall it Nu-Tool were better than most for vice quality, certainly my big cross vice is about the best example of the breed albeit still imperfect, so maybe one of theirs.
