An Unknown "american" And A Total Mystery - Identification Help

[Ryuluce]

So there are two pens I've procured in thrift shops that I haven't been able to find much, if any, information on. To help make the opening post no too huge, I've saved the photos to a dropbox folder and I'll link them.

 

So the first pen, an unknown "American" brand:

This pen is in fairly good condition, though I haven't given it a new ink sac yet. Anyways, the only labeling on the pen is:

 

The word "American" on the clip

"Made in U.S.A" on the pump lever

"Signature Pen 6" on the nib

 

Does anyone know anything about this "American" brand? Does this model have a name? What period is the pen probably?

 

I've been assuming that this pen is some generic brand without a model name.

 

Second, a complete mystery green striped pen:

This pen is the greater mystery of the two. I know absolutely nothing about it so any information would be helpful.

 

The cap isn't shown on the pen, because the cap I have is too large. The threads on the inside don't mesh with pen barrel's threads. There are two theories I have: either this cap went to another writing tool as part of a set, or it's missing parts.

You can't really see in the photos, but the top of the cap has a threaded hole in it. I assume that's where the top of the cap screwed in and held the clip in place. So perhaps the cap also had a band that was held in place with another screw in part? I don't know of any caps that did that, but it doesn't sound impossible.
Oh, there's also a small hole in the side of the cap about halfway along the length.

 

The nib reads "Warranted, Hi-Chrome Point, USA", and the section that holds the nib and feed doesn't seem to be able to be removed from the rest of the barrel.

 

I'm also curious about the filling mechanism. There are no remnants of an ink sac if there was one, and there's this weird piston thing. I couldn't easily find a pen online that had an identical mechanism. If anyone knows how this mechanism worked I'd like to know.

 

Yeah, this green pen is a total mystery to me. There are no other identifying markings. I'm assuming kind of similarly to the American, that it's some cheap no-name brand.

 

For this mystery pen, do you think it's even worth attempting to restore?

 

Lastly, if anyone has any questions about the pens that I didn't cover, let me know and I'll tell you what I can.

The filling mechanism seems to be a syringae.
