Galotta accordion

I am by no means a musician but this was offered to me at a low price so I took it. Cold war era, I'm guessing 50s, East german accorion. My problem comes when I try to find its type or another like it. The closest I've seen keep directing me to "royal standard" but I believe that's a seperate mark. As I understand it a few makers produced accordions from the same factory in East germany. I could be very wrong and it wouldn't even be the first time on this site. But from what I understand this instrument is somewhat scarce in the US and all research I've done on that tag leads me to believe it's an address to a music store.
