Clues

I was making tentative inroads into The Times mega-crossword (actually from Whitsun 1991, I have a book), and found the *best* clue:

Novel device for making moccasins? (3,4,2,3,8)

There's also:
Total satisfaction by close of play (4,4,4,4,4)
and
Unsuitable playmate for Ernest? (1,5,2,2,10)

Brilliant stuff!

Anyone want to help me out with:
Succeeding in winning the Dunmow flitch? (8,4,3,5)
