Here's what you can do to identify a 1926 Buick:
* Check for an engine number: Most early Buicks had an engine number stamped on the engine block. You might find this on the side or top of the block.
* Examine the chassis number: Similar to an engine number, the chassis might also have a unique number stamped on it. Look for this on the frame itself.
* Consult Buick historical records: The Buick Club of America and other historical organizations may have resources that can help identify your car based on its model, body style, and other features.
Remember, accurately identifying a 1926 Buick might require the assistance of a specialist or a Buick historian. Good luck with your search!
