Yeah, that is the system 3 tremolo I believe, I have system 1 single HB MIJ contemporary strat. It was what got me going on the HM when it came out. The contemporary strats were great guitars and have a following of their own.
I just saw one of these at the Guitar Center in Kirkland Washington last month. I also took a couple of pictures. The tremolo arm was missing the cap and it had exposed threads on the end. Same color and configuration as your photo. Same bridge too. I think it is called the Wunderbar I thought it was the same guitar until I saw the date of your post. It would be interesting if it actually was the same and had travelled all that distance over the period time.
