I got this meter a couple years ago and finally had time to break it down and put it back to new. Although it looks rough on the outside the internals were really in good shape with minimal corrosion (except the insides of the lower cast plenum that houses the diaphragm (pix to follow). Jack Sim has provided the necessary pieces to make it operate and look new again. His book has been invaluable. Thanks Jack (and Cindy too!) Before:

This is a 1948 model according to Jack and is the 2nd year for this model (Eco 97). There are a few features on this model (according to Jack) that are not found on later models. I'll point them out as I go on. Here are the guts broken down for mechanical and cosmetic restoration (notice the original brass bell after a bit of elbow grease and quad ought steel wool):

This pin is located at the top of the mechanism box and holds the top geared wheel in place. It is wire-tied to a small boss near it. I believe this pin went away in later models.

This copper "drain tube" which is behind the main valve is supposedly not found on new versions of the tireflators....

This is a "felt oiler" at the end of the tireflator spring that Jack has stated were removed from future designs or during maintenance....

Here is what was found in the diaphragm plenum. I'm thinking that the system missed a daily moisture purge, or two over the years! I used a strong concentration of muriatic acid to eradicate the rust on the inside of the cast iron diaphragm housing......

Insides getting put back together. I'm waiting on frame, shroud pieces, and base mount at the powder coaters for final assembly....

https://youtu.be/e3lAMWORJsYNot so good at embedding a video, but this link is a quick test to ensure the systems work. Surprisingly it was only off by one psi prior to calibration.

Nice progress update. The restoration looks like a first-class job. Make sure to post pics when the bodywork gets back from the powder coating place.

Always looking for grizzly gasoline stuff, or any Montana gas and oil stuff.

Thanks guys. Have really enjoyed working on this. The design is quite impressive and robust. Very few pieces needed to be replaced. I will have to leave the back end of the tireflator open to show off the mechanical visual features when its operating and in my shop. BTW, I am finishing up a refurb of my detached garage and the air meter will mount in this area....
