Your top image has a “German Handmade” at the bottom. It is shown with a bunch of Vitro Agate “All Reds” and possibly a few newer Marble king patch and ribbon type.
It is the same with the other images, minus the “German”.
The bottom image shows A Vacor at the bottom of the pile. It is the only vacor that I see and it is more than likely a “Red Devil”.
Mega purchased their marbles from Vacor—same thing really.
Marble—On!!

Thank you Akroorka

Got this lot and a whole lot more in a box full. I did manage ,from the link you shared on Vacor/mega that the Red devil was amoung the list. Again many thanks for your expertise.
