The body shape is very FW24 (2002) but if memory serves in 2002 i think the side-pod sponser was Compaq not HP ... they didn't change mid season did they? can't remember that.
At least it's not a 2004 (FW26) with that silly droopy nose
Technicalities aside i still say this is a cracking build, and yes i would have been swearing like a trooper trying to get all those decals to look decent like Harry has.
