I have had a couple of Hack Miller rods. One built by either Sewell and Dunton or Montague made out of Bamboo and in a 8' 2/1 Configuration for 5 wt. nice rod.
I have also had a Hack Miller Fiberglass rod but I don't have any photos of that rod although I know it wasn't Heddon built, I would love to see the Heddon.
Hack Miller was a sports writer her in the Salt Lake City area and liked to fish the Strawberry river. Most that information is available in a simple internet search, I don't remember much more about him.
Hope this helps a little.

This one is a Hack Miller Deluxe

Ziniks, I remember those days. that makes sense. I am not sure if they carried these rods but my thought is that they probably did.

Here are some pics of the rod :





To me - the writing looks very much Heddon. Brian
