Keilwerth-made Triumpf. Yes, it could be a really nice-looking Keilwerth copy, but I doubt it. Compare the engraving to this Super DES horn.
According to the original eBay ad for the Triumpf, the engraving is called "Die Frauengestalt" by a "Herr Reichelt." I tried to Google that, but I get too many results on that in German ....
Sorry I didn't reply to you when you wrote about this horn last month. Oh wait, it was this month... Oh wait... It was only 4 days ago... I suddenly don't feel so bad... I thought I lost a month out of my life here...
I tried to find some reference to "Herr Reichelt" & engraving, and came up with nothing. (BTW, "Frauengestalt" just means female character.) Then I tried the Google.de and came up with this thread on the German saxophone forum: (last post in thread)
Hallo Tomka,
dein Sax kommt sehr wahrscheinlich aus dem Musikwinkel
und somit müßtest Du eine Menge Detailfotos einstellen damit wir vergleichen können,
ob der Hersteller Kohlert, Köhler ,Adler,2x Hüller, Werner Roth, Keilwert oder sonst wer war.
CA Wunderlich wars nicht , der hat nicht hergestellt sondern war Grosshändler und hatte nur seinen Namen drauf.
Aber Du hast da ein Sax was Fritz Reichel graviert hat.
Er war der " Jason du Mars" des Vogtlandes, wenn man so will,
und hat für alle Hersteller graviert.
Mit seiner nackten Frau mit Weltkugel und oder Wasserfall ist er sehr berühmt geworden, die Gravour hieß zu seiner Zeit :
" Die Frauengestalt"

So the upshot of this is that the Fritz Reichel (note the spelling, eBay seller got it wrong) apparently was the "Jason Du Mars" of the Musikwinkel, and engraved for all the manufacturers in the region. Thus his engraving can be found on any of the horns produced in the region. This female figure with the globe was supposedly what made him famous and was known during his time as: the female figure.
Obviously one would have to do a bit more research to confirm all this, but this will give you a place to start.
