Worksman trike 1960's

My wife and I bought this about 12 years ago, and I replaced the hard tires with some whitewalls and rode it around the neighborhood for a while, then took it apart and threw it up in the rafters. The other day I decided to bring it back out and have some fun with it. I am gonna make a Bad Humor ice scream box for it. The trike originally was used as a mechanics cart in one of the Ford Motor plants around 1962. A truck in the plant run into the back rim and bent it bad, so the mechanic put the black rear rim off another trike on it. I got it for 60 bucks, two Matchbox car catalogs, and six postcards. Found the plate at another sale.
