The neck profile on Clapton Strats is NOTHING like that of the SRV Strat. The SRV Strat neck is a friggin' baseball bat, it's HUGE. The Clapton Strat model neck is thinner, and literally shaped like a curved "V". Both guitars are fantastic, but IMHO, the Clapton Strat is the better of the two.
A friend of mine bought a red one brand new in 1990. It was awesome, but never had the vibe of my '56
