That graphic was a regular/standard option on Blitz guitars, and the 3x3 headstock Blitz guitars are DEFINITELY NOT the more desirable of the two versions. I think the Floyd on that one is an aftermarket installation, but there is a slim chance that it was factory original. Floyds and the Sustainblock trems were standard fittings, and Kahlers could be ordered as an option. The wiring and mini switches are also 100% aftermarket, as Hamer's cavity work would bever have been that sloppy.
A fair price range to expect on that would be $400 or so on the low side (condition, alterations, no case) up to maybe $600 +/-. The Blitz is a fun guitar, but will not realistically sell for close to $1,000. Not any time soon anyway. Again, not a criticism of the ad, just the reality from somebody who has been buying/selling/trading HAMERs for well over 20 years.
