Hi Joe, Thank you for your wonderful detective work. I have searched through Riders and found the set : it is a Model 680 Hudson radio built by Zenith dated 1934.So the vibrator , rather than being a "it works so we'll fit it " substitute may well be the original for this set.This is probably an especially rare set in N.Z. Here in N.Z.  in the 1930s few people could afford cars and ,as in the U.S. ,the Hudson was a rare luxury car especially coming out of the Depression.There were ,though, many Essexs,the cheaper Hudson offshoot on N.Z. roads .So thank you again Joe. I'm so impressed with how you have narrowed the search down. The set is nearly going,but a stray loose wire off the top of the volume control had me foxed. I will let you know how it all plays out. Thanks.
