While the drum has been around a long time, ancient drums are not considered vintage. A vintage drum is typically a drum made within the last 100-150 years, though a drum that is only 15 years old could be considered vintage in some circumstances.
There is not a lot of information about many of a vintage drum though some of the best information can be found in catalogues advertising the drum from whatever year they may be. Catalogues for drums go back to 1902, though there may be older ones. This is the best place to identify these drums.
The best place to find a vintage drum is actually online, especially if a specific drum is desired. There are deals, and there are steals, and there is crap as well making it important to do thorough research and confirm the quality and condition of the drum before making a purchase. These are often hard to tune as well as find replacement parts for, so beware, but if a good one is found it can provide a long forgotten sound that no one is playing today.
