Era una pre-historic del 57 fabricada a finales de los 80.
Y para confirmarlo unas palabras de un currito de gibson que estaba por alli durante aquellos años
I can shed some light on this, I worked at Gibson at the time-The only Classics Slash got from us were a couple prtotypes from the Custom Shop. They can be seen in the famous group photo he did with a bunch of his guitars a few years back. One was trans red the other trans amber-both had a pearl TRC with a Slash tophat and signature, both were regular tenon and had 60 slim necks. Both had black chrome hardware and really flamey/quilty wood. I don't think he much dug them, never saw them anywhere but in that one pic.
The goldtop is one I know about, I remeber we sent out that 57 reissue for Slash and a Black Custom as well as a white ES175 for Izzy. All were stamped "Artist Promotional Use" on the back of the headstock, as were all the standard production guitars that A&R handed out-these generally were cosmetically flawed in some small way. That particular darkback pre-historic was an 89 model and was just a wall hanger in the artist "showroom" in the plant. Slash played it and asked for it. The guitar was a regular old short tenon, regular C shape neck model. The difference between a Standard and a reissue back then came down to only a few things that differed, it was basically cosmetic-The bodies had thin binding in the cutaway, the bridge was an ABR1 rather than a Nashville, the serial was inked rather than stamped, and the pearl head logo was a fifties style open"b and o" without a dot over the i. There was also no shielding can in any of the reissues-the can was phased out a little later on. Just a stock guitar like anyone could get back then, blemished, stamped, and plucked off the wall by Slash.
