Buchanans House Of Commons Scotch Whisky Vesta Case

A very unusual advertising vesta case for Buchanans House of Commons Scotch Whisky. Brass body with aluminium pressed insert showing the house of commons image. There is a slot on the back with an opening possibly to allow the small red vestas to be shaken out or extinguished and then slid back into the case?? One minor dent and some oxidation to the front case. C1900/10.
