Various sources seem to disagree on this -
Mike Lawrence's 'The Ron Tauranac Story' suggests that the 'Rosberg' Theodore was TR-2 - the one that won the chaotically wet International Trophy at Silverstone in '78... And that TR-1 was used briefly by Cheever.
'Higham' (first ed.) attributes all of these events to TR-1, with no mention of TR-2.
Don't have Autosport to hand; though, as ever with such matters, it's hard to tell which sources draw on which others.
Also 'post-Brabham', Ron T is credited with the Trojan T103 (a few GP finishes for Tim Schenken) based on his previous F5000, the T102 which, in turn, drew influence from an earlier Tauranac Brabham.
Despite their origins or heritage, I don't think I've ever seen any of those cars officially presented as Ralts.
