Martin Lane G1 flight jacket (1968): Correct thread(s) to sew replacement cuffs and waistband

Hello everyone,

I purchased a lovely Martin Lane G1 with mouton collar produced in 1968. Unfortunately the cuffs and waistband have been savaged by moths, they are brittle and falling apart. I have bought a replacement set in seal brown from Larry and have handed it all over to a seamstress. She will begin unpicking the thread shortly to remove the old set, and will sew the new set on, sewing the new thread through the original holes.

I still need to provide her with the correct thread...
