Tom, I wish I could recall but I had no problem buying them, perhaps Restoration Specialties or one of the specialty stainless suppliers like A I R Fastener, Packard Twin Six, Tioga Stainless? There were two head sizes, you've got the right (smaller) one for 1934. Also note some spark plugs have a metric stud thread and some may have US, so best check the plug thread before ordering. If I run across where I got them, I'll add to this post but you may hit paydirt with the 3 above, I generally find my needs at atleast one of them.
PS - Don't forget that the silver/gray high tension wire is correct for 1933 and 1934. Stock item by the foot from I believe Restoration Supply or Restoration Specialties.
