I've been over-supplied with a number - some 5 extra sets - of the lap-straps as pictured below, done at 1:4.5 scale. If these are of any use to people, please pm me your postal address, and I'll send 'em out (unpainted) if you'll cover the postage. They will need shackles - I use the 7.4mm ones from Prime-Miniatures, although one size up might have been better. Ian - if you read this, I'll put a couple of pairs in your next box of surplus/ superseded parts.
