I dont believe the Shoe Box came out in Chrome Base, only the Black Base....The other 2 are well covered in what ppl have said.....HW's common Errors....I used to collect the Errors but they are becoming too easy to find today....Back in the 70's - 80's they were hardly ever heard of....Shows how the Quality Control has changed.....Nice finds though if you collect them
