Smart yes, but when would you wear it?
They stopped issuing them about 1974. They were fine for walking to work at Waddo but if you drive or cycle they are an encumbrance.
Never tried to wear one with a pully.
Like a No 1 they are fitted as well.
So save your money they are just too impracticable.
You could try for a British Warm in Air Force blue. They are far more practicable. Shorter length and you can remove rank tabs when travelling.
