Frank Spencer Type Coat/Long Belted Trench Coat (Hutton BS24)

I'm after long belted trench coat in beige/green/brown.
If you are lucky enough to be old enough to remember Frank Spencer, then that is exactly what I am after.
It is for use in a pantomime, so can be any condition!
Ideally men's, small or medium, chest size 36 to 40, but will take whatever is available!
