Can someone with a Colt 1917 please measure the thickness of the ejector "arms" for me? I am trying to figure out if the ejector star is the same for .45 ACP, .45 Colt and .455 Eley. Numrich lists only a single part number but I'd like to be more sure.

No rush at all. This is a back shelf project.

Thank you!

I can measure mine and let you know. I don't have it in hand right now. If I forget or don't get back to you in a couple of days send me an email to remind me.

I'll try and measure mine too. Might be tomorrow evening but I can do it.

I measured mine. They are about .080" thick +- near the ratchet, and they taper to about .070" at the tip of the star.

My New Service was originally a .455 Eley which had been 'shaved'. I sourced an untouched .455 cylinder with ejector and rod. However, the ejector star does not screw down tightly, as if the threads are stripped. Fella on GB has an ejector for a 1917 and I was hoping they were the same beastie. Mine measures just as yours does.

Thanks again!

Glad I could help, and that they are the same. That will make life much easier. Merry Christmas

Sounds like you got it figured out. If you want me to go ahead and measure mine, let me know and I'd be glad to.

If it's no trouble, yes please. That would give me 4 data points: yours, Jared's, mine and Numrich's single part number. A feller could be pretty certain with that!

Then it comes to fitting it all up. I have brass and proper hollow base bullets. It ought to be some kind of fun!

Mine are about .075" at the ratchet and taper to about .065".

I'll take -.005" as being 'within tolerance'.
