1914 Model T touring

[Royce P]

The reference books are referring to the motor number. This is not the number on the firewall patent plate. Your engine block has a casting date. The car would typically be shipped within a week after the engine block was cast.

My car's ship number is 409023. Would it be safe to assume it came off the line sometime in mid January 1914?
