I found out about you from doing research online about Duplex drums. I have a very old snare drum that Im holding for a friend of mine. It is a nickel/chrome perforated snare drum from Duplex with a presentation badge on it. It says “Presented to Mr V Platz by his friends and admirers July 3rd 1892. Its a beautiful drum and appears to be all original. Do you have any information you can share about a late 19th century Perforated Duplex snares or about Mr V Platz? I look forward to hearing from you.
