HighMasK carpark lighting

Sadly this is long gone, but these highmask fitting look like ones i saw in FSB photo on LG. G.E.C. Z3430. This been most interesting fitting that I grew up with in old Albertsons carpark in San Antonio, Texas, i could never figure out what they were until FSB post came up on LG. Albersons packed up in 2001 and sat empty for two years until HEB grocery bought building they keep these until about 2 months ago for all LEDs. I remember these being relamp in mid 1990s they had philips 1000 watt MH in them. But they were orginally MV lit. And I know these lantern been around since 1972.
