Vintage drum badges can be hard items to source and sometimes expensive. I have a collection of items in stock with brass and steel grommets to match which can either be shipped or installed as required. Bass drum logos are also available as vinyl cut or I can hand paint if required. If custom hand painted bass drum heads are your thing please give me a call to discuss.
These two websites: http://www.vintagedrumguide.com and http://www.drumarchive.com have been valuable resources to me over the years. They contain a large historical catalogue and will help you find out exactly what it is you own! Visit my Projects section here as well for more examples of work.
