1976 Worldwide Entertainment Systems

[old_tv_nut]

I hope this is the right place, because the only forum that mentions projection is "Early Black and White and Projection" -and this is projection, but not early or black and white.

Well, anyway:
I got this 1976 ad for a "Worldwide Entertainment" brand self-contained front projo. It seems very similar to a Sony KP 5010:

but you can't tell for sure because it is shown folded up in its storage position such that the lenses are not visible.

Anyone know anything about these? Were they re-branded Sony's, or??
