Default Can anyone ID this S&W part

I feel sure this came off of a S&W DA barrel assembly that I once had but I am not 100% sure. If anyone can verify it for me I would appreciate it.

Is it possibly from a top-break revolver?
It presents itself like one of the parts at the pivot point that actuates the extraction motion, but with nothing to reference the size of this, I really do not know. Just a guess.

It's part of the ejector cam assembly----the big part---found in most top-break handguns----fits in between the ears of the barrel at the hinge.

Don't leave home without it!!

It is an extractor cam, and I think it may be from a non-S&W top-break. Early top break S&W cams had extractor teeth and later 32 & 38 caliber SA and DA top-breaks had a different shape as far as I can tell from your pictures, but there is no scale to compare size. I might be wrong, but don't think it is a S&W part. There were dozens of top-break revolver manufacturers out there made from the late 1800s well into the Twentieth Century, so matching up the part with a particular manufacturer and model will be difficult.

Looks like the extractor cam from an Harringnton and Richardson .32.

The shape/contour of the cam protrusion is different than that found on S&W pieces. Similarly, the surface finish appears much rougher than that produced by S&W---although a combination of wear and the significant magnification provided by the photos could be the culprit here. Finally, we're shown both sides of this piece, and neither shows the slot for what I'll call the sliding bar and spring to be found on S&W's (with this type of mechanism).

Bottom Line: I don't know what it's for, but I know what it isn't for.

Gary & Ralph are correct. It's not a S&W part. Ed.

Do you have an Harrington and Richarson top break? Or at least parts of one?
Because that thing surely looks like the extractor cam of one of them.

Wow it's good to know I'm not the only person to take a revolver apart and put it back together with parts left over .

Well, when you get REALLY good at taking apart and putting back together, you won't have anything left over. What you will have is something that either doesn't work like it should---or doesn't work at all.

The latter situation arose during my latest disassembly/reassembly boo-boo. I reassembled a rear target sight (spring/blade/screw), and it worked just fine. I'm almost finished. The last step was to install the cylinder stop plunger/spring/screw---a piece of cake---except the cylinder stop didn't work at all---just sat there---no down and back up---no nothing.

After a suitable period of sitting and staring, it came to pass that the sight will work fine with the cylinder stop plunger spring in it----and the cylinder stop won't work at all with the sight spring providing the power----'cause it's it's just a tad shorter.

The moral of this story is you live and learn---if you live long enough.

Thanks guys,I thought it might have been for a S&W 44/40 barrel/cylinder I once owned but it must have been with so odd parts I had.

To be sure, why not send the photo to S&W CS and ask them.?
