That style of safety interlock cord isn't too hard to find, they were in common use right into the 1980s, or later, I've salvaged them from assorted junk electronic items over the years. The hard ones to find are the types that have ears that are riveted onto a bracket on the back panel. One thing to watch for is that import items sometimes used different spacing between the pins, or different pin sizes from a North American item.
