Question regarding a custom action?

[Philly]

So I accuriered this action along with a couple more from a friend before he passed away. He didn't give me much info about them. they aren't quite complete but wouldn't take much. But my question is, Does anyone know anything about them? Says Cooper on it and from Houston TX. Thanks.

Very interesting. Sorry, no help here.

Made by Wilbur Cooper. He was involved in the Houston Warehouse testing.

Neat looking action! Have one for sale?

Possibly

Retired Benchrest Shooter John Jones in the Houston Area might still have one of those.

They were involved in the Houston Warehouse. The one John had was pretty crude.

I haven’t seen John in some time. I can get in touch with Vic Smith, who does talk to him periodically.

One of our local BR shooters that recently passed has one of those Cooper actions. He told me about it on several occasions but I've never seen it. He told me that about 40 were made.

That's good info. This action isn't really crude but more " blocky" maybe. Still needs a couple things to be operable but its kinda neat.

I'm trying to figure out if this is no 2 or maybe 21?

Yes, interesting. I don't see anything resembling an extraction camming surface there.

Sorry for my ignorance but could you explain?

Here's a pic. There needs to be a means to start the extraction of the brass from the chamber as it can get rather tight. These simple camming surfaces offer leverage to break the tapered case from the tapered chamber walls, to ease case extraction after firing as the bolt is rotated open....in simple terms.

Thanks. Makes total sense now.

I noticed what looks like angels on the bolt lugs, any idea why it has that design ?

You have to have some sort of closing cam to close the bolt. Many homemade actions I’ve seen put them on the bolt lugs since it’s far easier to do there than inside the action on the lug abutments.

I said I didn't SEE anything and I still haven't maybe as you insinuate, it has something but it's not apparent and it wouldn't be the first action that I was asked to evaluate that lacked such a simple thing. Simple to me and you is apparently not so simple to those that simply don't know.

As to an extraction cam, you can’t see all of the action and bolt handle slot in the pictures. There may be a cam that acts on the corner of the bolt handle. You can’t see what you can’t see. It’d be interesting if the OP posted a picture of that area.

I didn’t know myself if these angles on the bolt lugs had anything to to with cocking or ejecting, that’s why I asked.
I was just trying to learn.

Those are meant to act as closing cams to help get the action closed and possibly the last bit of cocking after the sear starts to engage.

Maybe the stamping is no.2L (long action)? Looks like one. Curious what the boltface diameter is.
