Wanted a single N-3B parka button

[RAPPLEBY2000]

recently I bought a N-3B parka from a charity shop, lovely jacket in perfect condition but sadly one of the big grey front buttons is missing.
I've looked in local sewing shops and they don't have anything even close.

It's a (genuine) sage green version circa 1978 (if that matters)

can anyone help?
cheers
Rich

cheers for looking, the buton in question is a few mm over 1" wide, four thread holes,
almost identical to the 1980's arctic DPM windproof button but the wrong colour

the jacket colour is decribed as sage green a sort of greyish green (not olive green).

thanks
