Two cars are sold new where I can't find a reference to chassis number. One of these is to de Adamich, which isn't raced in 1973, the other to Takahashi Yorino in Japan - presumably these are accounted for by numbers 8, 10, 11
I can't tell you which works car was used in which race.

All numbers come from a mixture of Motoring News, Autosport, F1R and NZ Motor Action.

I just noticed a couple of things from Autosport reports that might be new. When Surtees enters two TS15s at Rouen in 1974 for De Dryver and Dieudonné and then withdraws them again, the spare TS15 then used by Watson for the race is said to be ex-de Adamich. Then at Mugello, Dolham's TS15-Hart is said to be ex-Mass; it's not clear whether this is a different one to the TS15-Hart he's driven in preceding races.
