The one used on Streets on the Vertigo tour originally had a diffrent color pickguard if I recall.
If it is truly a 1973, and wasn't a custom order back in 1973, then it would have originally had the 3-layer pickguard and white pickup covers.
The black pickups and pickguard wasn't a stock option until 1975 (black being the pickguard color of choice, vs. white for 1975-1981, if memory serves).
But from all accounts (magazine interviews from Vertigo tour through the Music Radar online article of 2009) the all black Stratocaster used for Streets on Vertigo and 360 is the all-black 1973.
