mrktnsl,HRichard, Although HRichard has graciously offered his assistance, I'm not sure duplicating his measurements is your best option. I question that his empty case ejecting rod shown in the photo is original. The most evident feature being the nose or muzzle end of the rod. What appears in all the Model 1s in RHMC24's photo shows a bullet head shape ahead of a shoulder. That shown on HRichards appears as a bullet head shape followed by a V cut groove. Secondly, the photo appears to show a screw at the base of the rod, a feature I have not seen until the 3rd issue Model 1s. Thirdly, it is difficult to measure the length of the rod from the photo, but it looks just a mite long.

The ejector rod on my Model 1 Second Issue measures exactly 1 1/2" from the bullet tip to the barrel frame, on the bottom side. The rod is .225" in diameter.

Your revolver looks like a very nice example. Good luck finding a replacement or making a new ejector rod.
