My uncle has a 1924 Walter P Chrysler. The vin plate was manufactured by Fedco Systems and there's a signature of WPC across the plate. the numbers are written in long hand and are repeated. they appear to be 0204E. This is a two door sedan and I dug up a Saturday Evening Post Article from 1924 where WPC is pictured with three cars. I believe that my uncle has the sedan pictured. It has the same pin striping, colors, etc. How can I verify the vin number, or otherwise prove that this is a WPC original prototype. I think that the numbers may be Maxwell's vin numbering system. I'm also trying to establish what this vehicle may be worth. I still have to figure out how to send the attachment to this board.
