Unknown Ollendorf Watch

[Dpastl]

So I just picked up this watch from Ebay, thinking it would make a great special occasion watch.  I figured I'd be able to identify the movement after disassembly but I'm afraid I'm just as lost as before.  Does anyone have any ideas on what this could be?

What I know:

It's an Ollendorf movement.  Ollendorf was an importer of watch movements.  They have a cool logo.

The only markings are a 315 under the dial, which doesn't appear to match any movements in the Ranfft database.

Any help is super appreciated!

Oh, here's the dial.

Ollendorf also owned gotham watches it seems and I've found a similar movement from an auction on ebay.  Seems like they imported a number of movements from a particular manufacturer in Europe, I just don't know who as the style is unfamiliar to me.

As a note, I found a forum post by Dr. Ranfft that suggested ollendorf might import from AS, FHF, or Felsa.  I searched through his database for those manufacturers and didn't fine anything.

Bridge layout looks somewhat diferent, cock pins may be furthure apart on your movement.

Has the looks of FHF family.

I found one very similar an AS635. How wide is the movement? This one comes under 24.75 - 26.75 mm

does not show back, so can not compare that. And Google searches i found nothing except spare parts for that one.
