Vintage Bank Midwest National Insurance Companies Piggy Bank Collector No Key. Old insurance company piggy back. Usually given away to policyholders as a premium to save premiums! Unfortunately no key but probably easy enough to find a key or open up if you wanted to. Nothing inside that we can tell. You get it as we found it although we did use a bit of brasso on the front to better read the name. On the top there is (we think) ?MWN? which would match up with Mid West National. Bank is 4 inches in height and 4 inches squared. And heavy. Probably circa 1920s-1940s as later ones would have been mostly plastic. Will ship USPS with tracking to winning buyer
