Hello!
Thank you so much for your help. We have a message from Csmarshall: he found out the name of the manufaturer. Thank you!

Manufacturer was the company of [b]Gebrüder Schoenau, Swaine & Co.[/b] from the town of Hüttensteinach near Sonneberg in Thuringia/Germany. Shown mark was used between 1924 and 1930.

I could not find your mark. Not in kovels or U.S.A P&P book marks. So it’s either too new or from a private studio or made over seas.

Thank you for your reply, I will look in my books of marks and get back to you.
