Effective period / Period of releases: 1980

Seemingly a fictional orchestra name.
At least some of their releases can be attributed to the Czechoslovak Radio Dance Orchestra, for example “John Henry Borland And His Orchestra - Famous Western Film Melodies”.
Other releases were probably compiled from recordings by other Czech and Slovak radio orchestras like Pražské Smyčce, Brno Radio Pops Orchestra, Czechoslovak Radio Dance Orchestra Bratislava, and others.
