I'm also into finishes that will last the longest and protect the metal of the horn the longest.I think in general the colored lacquer gets a bad rap.
Maybe because there are so many cheap horns doing it?
Miles Davis played a red Martin Committee trumpet all through the 70s yet collectors shun this model like it has Ebola all over it.
Even various finishes (matte, antique, etc seem to have less value, maybe because they are just less "normal", like a custom built house Vs a cookie cutter, bigger resale opportunity.
I think if it plays well and looks nice it, it's cool.
Sadly this horn the OP points to isn't either.
The first black horn I saw was a Guardala "New York Series" with all the engraving in the mid '90s. Check out the Conn "enamel" finishes like this one from 1922:This thread makes me curious which company or brand was the first to offer different finishes other than the standard gold lacquer or silver plate on saxes other than an occasional "special edition". The first ones I ever saw were Cannonballs, but that may be because I live in "Cannonball country" and did repairs at a Cannonball dealer. I remember seeing a pink Mark VI tenor at the Musical Instrument Museum in Phoenix. It was "remarkable" to say the least.
I don't understand what you mean by "accepted ORIGINAL color". It was certainly not a standard offering - custom, yes.Pink was a accepted ORIGINAL color for a mark VI, I don't see anything weird with any color, if this was good for Dexter Gordon so it is for anyone...
It came from Selmer and wasn't an after market job and it was in the range of offered colors. White, Black , Blue and Pink. So it was an original option, not a unique custom work. The definition of custom may very but there have to be at least a couple of dozens around.
There is also a small number of blue lacquer Mark VIs ... made in the 170k serial range
Saw this Conn listed for sale last week by an auction I watch. Did not see it, but my best guess was it's original colored enamel.I know Conn was offering colored horns in their catalog back in the 20s.
