Yeah, I've read some discussions about this on other forums - I think the theory that the "K" serial number Orvilles were MIK has been debunked quite recently, and the Japan Guitars guy has updated his site to reflect that.
Sounds right to me, I have an Ibanez bass that is stamped "K" in the neck pocket and I thought it was made in Korea but the folks at the Ibanez forum assured me it's a made in Japan model, possibly the same factory as the Orvilles.
Incidentally it's one of those MDF, err, I mean
Resoncast models they made for a while
