On ebay.com, an "Antique 1924 Ludwig and Ludwig Double Bass Drum Pedal" is listed, item number 280790851158. It appears that two beaters could be employed simultaneously. One beater is missing. I have never seen such a pedal before and am intrigued with the mechanics of it. It certainly is a beautiful looking piece of vintage workmanship. If anyone knows anything about such a pedal, I certainly would be interested in learning more. Thank you. John?
