"World Famed Antoria Accordeon"
This badge is interesting because it provides what looks like a patent number, or manufacturer's number, as well as a statement that that accordion was built in Saxony. Most accordions just say "Made in Germany" so this is all helpful information to anyone who wants to find out which company built Antoria accordions.
"Fr. Gessner"Friedrich Gessner doesn't get much cred today, probably because he sold his company to Matthias Hohner. But throughout the 1920s and as late as 1932, Hohner made an accordion named after Herr Gessner. There was another Fr. Gessner from Breslau who made brass instruments, and I can't tell you if this is the same man or not. Any ideas on that?
Excelsior was one of those names that has been used by a few different companies. For my money, I'd wager that Hohner built this accordion. I could be downright wrong, but Hohner used a similar 6-pointed star on the spoons, stops, and cabinets of some of its one row accordions.
"Lubas and Son"
This ornate badge is from a Slovenian helikon built or sold by Lubas and Son. There are plenty of similar helikons floating around the auction sites, if you are interested to buy one. I have seen at least one other helikon with this badge (cherubs, trumpets) but with a different name inscribed within the plate.
"Hori Smoku" Sailor Jerry.
Another accordion badged Excelsior.
"Gebr. Ludwig's Accordeon"
With the famous pine tree trademark, shown here on both the metal corners and the stops. What is more interesting, and what also commanded the higher price at auction, is the plate between the corners telling of the dealer that sold the accordion. It appears the S.G. Street was a dealer for Ludwig in the early 20th century.
