The clue to 7 across is "1995 Japanese GP circuit (4 letters)". I am sure the answer is "FUJI" but this does not fit in with the letters I have -?I?A. I am pretty sure that the letters I have are correct - the "i" coming from 1 down "Multiple tube chassis (8 letters)" which I think must be "Birdcage" and the "a" coming from 2 down "Ferguson's tractor partner from 1957 (6 letters) which must surely be "Massey". Does the Japanese circuit "Fuji" perhaps have another four letter name which would fit in with what I have?. Any suggestions would be much appreciated.
