WW1 WW2 Welsh Guards army officers foul weather cape

For sale here we have a very rare Welsh Guards officers foul weather cape, bespoke made with a nice big stand up collar and orange / red lining. The cape also features the original buttons. There can't be many older than this one in existence. We have been reliably informed that they were part of the uniform for officers from 1915-1952 and this is definitely at the earlier end of that and has been well used. 

Fit - impossible to say but no army man back then was over size 40 and most were 36"

Condition -Ok, it isn't ideal but the button wear makes us think that this was a very early example and would have been used in service.
