I'd guess the Meopta lenses were made by Meopta. They had been making their own lenses for enlargers, cameras, professional movie equipment and the military (their biggest customer) for a very long time. Their lenses have always had a good reputation for performance at reasonable prices. Ditto their enlargers.
If there is a connection to Schneider it is probably Meopta supplying lenses to Schneider.
Meopta's current business is optics for military applications, some consumer binoculars and rifle scopes, and custom OEM optical assemblies. They are out of the consumer photography business.
The Anaret lenses from Freestyle are probably NOS from the 80's. That doesn't mean there is anything wrong with them. Most enlarger lens designs are from that era. The Anaret price is a bargain.
Also look at ebay for El-Nikkor, Minolta, Rodenstock and Schneider lenses. Unless you have money to burn I can't see buying any of these lenses new.
