Help needed

[Doti B]

Have come across these two razors while at my in-laws. They could do with cleaning up a bit and probably haven’t been used in ages. Can anyone help in identifying what they are as I have no clue.
Thanks
I was thinking a Gillette Slim Twist on the left and maybe some kind of Gillette Tech on the right

Left is a Super Slim Twist, right doesn’t look Gillette.

The other one is a two piece Soluna (Czech).

Ok thanks. Will try and dupe the father in law to giving them to me in exchange for a pizza
