alright this is strange to me
I was researching southern pacific paint schemes trying to figure out specifically what diesels wore my 2 most favorite espee schemes the black widow and the halloween scheme when i fell down a rabbit hole and discovered a lot of experimental schemes that Espee was toying with for the Rio grande merger. i saw hand drawings for some from an old 1989 magazine. two of them actually bore similar elements to the black widow scheme. from what i found the SP had a primer unit that it would paint up in a test scheme and photograph then repaint into another scheme and repeat the process.
its a shame the SP never picked one of these special schemes because they all look better than what we actually got but the costs of such paint was probably to much and the espee was already struggling enough with having to be purchased by the rio grande
i plan on making one of these schemes the scheme for my free lanced Fenix Pacific if not use all 3 for different eras of my railroad
i will post links to these images hopefully i don't get in trouble
