Yeah--I found that after you mentioned it. I think it is pink irl--that's too pepto bismol to be just a bad photo. Gibson did use a "salmon" color on some other 50s lap-steels--this could be "transitional" or "grabbing what's to hand on a summer Friday afternoon" or it might be a "mod" where someone re-sprayed the part pink because they saw the other hardware and liked it and the original BR-9 part was damaged (or not)....
Pretty sure that's how the hardware was colored (like Gretsch pickguards), with a clear acrylic part sprayed the desired color on the "back" side; at least that's what it looks like on my BR-9.... Ugh--looked closer--that's clearly "textured paint like on the BR-9's cream body, not the back-applied finish as on mine.
And it really doesn't look anything like the" salmon" on the Century, as here:
I'm leaning heavily towards "modded" (czech the (probable) non-original knobbies as well)
and, sad to say, fuglyumbus....
