Coke

I have a coke machine made by vendo believed to be a 1958 machine, however, it does not have rounded edges.  If you could help me figure out what year my machine is, I would be greatful.  Only information availible at this time is serial and model number which are H63 A. and 9021923 No picture at this time but hope to have one soon.  Thank you, Josh R.
