Just a reminder that Packard and some other auto mfgs of that period used SFE type fuses. The SFE fuses all have the same 1/4" diameter but are different lengths depending on amp rating. As an example, the holder in the photo appears original. If so, the OD calls for an SFE 30 which has a length of 1 7/16". The Electromatic on the other hand calls for an SFE 9 and that fuse would have a length of 7/8".

Point being modern type easily available glass fuses are usually 1 1/4" long and will not fit in most of the original holders. Unless the holders have been changed you will have to source the proper fuses or wind up changing holders to modern. NAPA carries SFE fuses as probably do other parts stores.
