It's probably the Minichamps factory Rothmans version of the FW16, I have one too that I purchased in the late 90s/early 00s. The car would have looked the same for the season-opening Brazilian Grand Prix (which was a DNF for Senna), so I like to say my model represents that race. The only other race of the '94 season prior to Imola was the Pacific Grand Prix (at Aida, Japan), where the car had an extra rear wing element that jutted forward of the main wing.
