What brand is this mic?

I recently acquired this beautiful Bottle/Tube mic from a life-long collector. I thought is was either a Neumann or Telefunken Bottle/Tube mic circa 1940's, but Klaus Heyne says it's neither. It has very good machine work, heavy gauge stainless steel, but electronics have been removed. I liked it just for the looks and condition, but would love to know who made it. (2) photos attached.

It has a look that reminds me of the Telwa bottle mics, but it's also not exactly like any of them I've seen pictured... so just as good a chance it has nothing to do with that!
Still, I figured better to mention than not.

It's hard to believe that not only the amp but even the capsule has been removed from this mic. Have you had a chance to open up the head and look inside? It could give a clue.

This element is inside the top capsule. Does that help to identify the maker?

The picture does not show this clearly , but it looks like a dynamic.
Is there a voice coil attached to what seems to be a domed diaphragma ?

Hard to tell for sure from the photo, but it looks like an aluminum diaphragm with a drive pin attached in the center.
That would likely make it a crystal (or ceramic) or controlled magnetic. The diaphragm looks very similar to the diaphragm on the old Astatic D104 crystal capsule (MC320). Of course those capsules have a huge resonant peak around 2500 Hz. The MC320 capsule in the D104 had a thick piece of fiberglass insulation (aircraft insulation) on the front to dampen the peak.
