Truth has to be said, it didnt start this way.

The dial did have radium on it from first owner. Technician working in the dark?

And… the original case is this:
/vgforum/index.php?t=getfile&id=10562&private=0

The case markings are more consistent with being made in-house with Gruen.

Personally I have no doubt that this is a Weber case.  The serial number suggests as much and this is a style of case that Weber definitely made.  Here's the same base case (rounded shell with incised lines) but with added crown guard elements in 14k that is marked Gruen-Weber:

I'm not in a position to say anything conclusively, but I now believe that aside from the occasional American gold filled cases exported to Alpina, Weber was Alpina's sole supplier of cases for the Alpina-Gruen line of watches.  If it wasn't Weber exclusively, it was darned close.

Just to be clear.... I think the goldfilled case that was "original" was Gruen made. The marking "Cased and Timed" says to me that this was a US made case.

That looks stunning. Kinda, sorta was thinking the silver one was Weber. What I dont understand is why would they put weber inside the solid gold one and not in the silver one. Is there some trend?

Got it.  I was overlooking the original case.

There seems to be somewhat of a pattern, but nothing that I can really nail down with any certainty.  You rarely, maybe even never, see the Gruen-Weber marking on a silver Alpina-Gruen case.  You often, but not always, see the Gruen-Weber marking on solid gold Alpina-Gruen cases.  I have two solid gold Alpina-Gruen Techni-Quadrons, one case is marked Alpina-Gruen, the other Gruen-Weber.  But why?  

The closest I can get to a rational hypothesis is this.  If a run of cases was intended for potential dual use as both an Alpina-Gruen model and a Gruen Import model, they would be marked Gruen-Weber.  If a run of cases was expected to be used strictly as an Alpina-Gruen model, then they would be marked Alpina-Gruen.  This would also be a plauisble explanation for why silver cases never bear the Gruen-Weber marking.  With one exception that I can think of (the brancard), Gruen didn't offer any silver Techni-Quadron models.  So it would make sense that none of them have the Gruen-Weber marking if they were only used for Alpina-Gruen models.

Sounds plausible.

In my excel and online search all silver technoquadrons have gruen alpina.

Was silver less in vogue in america compared to europe? Or… silver is ok for simple case designs, but elaborate cases need to be gold or gold filled? And taste is europe had been more conservative.

I think the answer is undoubtedly yes.  In the 1918 book, silver is still the usual choice for a less expensive wristwatch case.  By the 1920s silver is almost entirely replaced by gold filled cases.  And not just Gruen.  Elgin, Hamilton, Waltham.  Even Rolex in Canada.  For some reason all of North America settled on gold fill while Europe continued to offer silver cases as the less expensive alternative to solid gold.  What I’m unsure of is whether there is some regulatory explanation or if it was simply a matter of regional taste.
