First, i want to apologize that i will write in English, but my German is really bad. I am from Bulgaria. Yesterday i saved one Helicon from the scrap and i want to restore it. I want to ask here for more information about the brand, system and any kind of information. As you can see i cleaned the logo and it seems to be some blazon with two lions and a crown(?) It seems to be like the Bulgarian blazon from 1881-1927, but Bulgaria never made musical instruments, so it is probably purchased from somewhere.
Any info will be superb. Thank you in advance.
