My father gave me one of his old revolvers the other day, and the ejector rod spring and bushing appear to be missing. It's sort of a project gun because while the rifling and revolvers appear to be nearly perfect, the bluing is quite worn. The action works flawlessly.

I found a parts listing for the King Cobra which is essentially a Trooper MK5 if I remember correctly. Does anyone one know if the Cobra parts will fit the MK3?

Thanks

deputy, I found Colt Trooper parts on Ebay for a cousin. That is one place you can look, but you need to keep checking back for a while. You never know when someone will list something. I found a new Mark 3 .357 barrel for a great price, it was luck and timing. (Sure made my cousin happy.)

Thanks. Can you tell me how to remove the cylinder on this weapon? I can't find anything online. Or general disassembly, for that matter.

There is a website for Colt parts. www.coltparts.com The American Rifleman has featured lots of exploded parts drawings for all types of firearms in the magazine, so you might try there, maybe you can even find something online through the magazine. I never looked online, for American Rifleman articles etc., but everything else seems to be online.

To remove the cylinder and crane from the Colt Trooper Mk III (aka a J-Frame) just requires the removal of the crane lock screw. Once the screw is removed, open the cylinder until the crane stop rests against the frame. Then, rotate the cylinder to align the closest flute with the raised crane guide at the front of the frame. Then draw the assembled crane and cylinder forward and clear the frame. That's it.

If you plan on rehabing your Mk III, you might want to invest in Kuhnhausen's "The Colt Double Action Revolvers: A Shop Manual, Vol. II". It's well worth the investment.

a screw opposite the cylinder, which would be the left side

The King Cobra parts as well as the Colt Trooper MK V parts will fit the Trooper MK III. When you remove the crane lock screw, there will also be a spring and lock plunger that needs to come out before removing the crane/cylinder assembly. Gun Parts Corp. should have the parts your looking for as well as Jack First, Inc. J.B. Wood's book, Revolvers Assembly/Disassembly is an excellent source for complete disassembly of your Trooper MK III. As noted above, Kuhnhausen's book, The Colt Revolvers, A Shop Manual Vol. 2 is also a great reference. As a gunsmith, I have all of Kuhnhausen's and J.B. Woods books and use them often in my shop......................Dick

Yes, the parts should fit. A friend recently purchased a king cobra with a slight timing problem. The plan was to obtain parts and correct the timing. After a few months of searching, he has almost given up the hunt. The parts just ain't there. Good luck and hope someone can provide a source for these parts.
