Packard Bell Phonocord

I was wondering if anyone had some more information about this old Packard Bell Phonocord. I believe it was capable of recording 78 records. All I have been able to find out about it is that the microphone included with it is apparently THE best microphone for recording harmonicas. I have no idea if it still works or not. I inherited it from my Grandmother who used it to record music with her swing band. So I'm thinking it's from the late 30's to mid 40's somewhere in there. Any information anyone might know about it would be much appreciated!
