Really nice HBG and HSB QA! I see the HBG has a big split in his tail too (that's not typical, right?). Somewhere on the forum (almost as bad as saying 'it depends') I read that LMB can by uniquely identified by their spot pattern. Maybe HSB too? Since you now have a photo of the left side of this HSB, maybe you'll catch it again for a comparison shot. Hope so! The pattern looks like the digital display on some stereos, where you can adjust the tone and bass and mid levels, etc. He didn't have any music coming out of him I hope?!?
Sorry, guess I'm channeling my inner JHAP today.. ( I loved reading his posts)
