Ingraham mantel clock identification
Ingraham mantel clock identification uses the case model and movement wording; a patent date names an invention, apart from the assembly year.
Case label and movement
Look on the case back or interior for a paper label and on the visible movement plate for company wording and patent information. The movement and the decorated case provide different clues; a patent date names an invention rather than the assembly year.
What to check next
Copy the model name and full company spelling. Compare the dial, case profile and movement type with that model. A later dial or replacement movement should be recorded as a separate marked component.
