The Robert Dollar Steamship Co. - - -

- - - - Apparently owned Heintz & Kaufman the famous early transmitter manufacture:

Which is just one of the interesting aspects surrounding this latest restoration.
With ties to the Dollar logging operation in Portland and other West Coast cities, this radio, or at least most of a radio, is another fine example of western manufacturing.

I'll let you read the listing above for more background. Here, is the 3 tube detector and 2 stage audio amp:

If you look carefully, you'll see the mistake the engraver made by placing the word "BY" in the wrong place and then engraving "Robert Dollar Company" on top of it.
Picture
Heintz & Kaufman was not known for making consumer electronics. It is almost a sure bet that this apparatus was installed in one of the Dollar Steamships. It was probably accompanied by a matching tuner section that would have been hooked by buss wire to the "TICKLER" and "RA RE" connections since this is just a detector/amp (DA) with no capability of tuning except the presence of an 85 mh choke.
Picture
It looks like the manufacture attempted to prevent corrosion in a marine environment by using enameled buss wire and coating all of the connections with a black substance. While this did preserve the connections - internally, the external connection hardware had a noticeable amount of insulating green crud that had to be cleaned prior to testing.
Picture
I am happy to report that the "Detector" stage hummed when touching the RA terminal (RE to ground) and each of the successive stages hummed louder, which is all you could expect missing the tuner.
Picture
This is probably a very scarce item, but I am hoping to find the Two missing knobs.

I am, today, working on a single stage tuner. Once it is completed I'll see how it sounds coupled to this unit.

It is possible that this radio was designed primarily for CW reception. I believe that it would have been manufactured in early 1925.
