Funny, I was just going to post that.

Another reseller listing, it's for sale in Japan for 950 USD.
A beautiful and rare guitar (the original Japanese sellers, Ikebe Music in Tokyo, seem to specialize in those, I bought a super-rare Greco SE with a bound neck from them just a few weeks ago), but it's interesting in another sense as well.
I've often wondered what happens when model number "collide" through adding custom features. I mean, add a custom finish to a JB-45 and it would become a JB-50, right? The trouble is that the JB-50 is also another and different catalog model.
Going by the U-stamps (assuming they're original, of course), this one would be an ST-50 with a custom colour (+5k yen) and a matching headstock (+5k yen), which adds up to a 60k price tag. So there's a "collision" with the standard ST-60. As I recall, this is the first time I've seen one with a technically "wrong" model number sticker still in place.
