Check out the album under "Photos" about the enclosed Maxwell LD.
There is an example of a 1909 Maxwell LD Runabout here in Australia which has a door fitted to the passenger's side and a panel fitted to the driver's side very similar to the treatment of the AC Messenger. Identification number LD8914
Both the door and panel are sculptured to fit the shape of the body. The door is swung on hinges identical to those on an AC Messenger. The car retains the brass threshold plates riveted to the door openings. The door merely closes over it.
Whilst this was a curiosity, it was most likely that a previous owner paid a body builder a sizeable price to modernise his car. It was a one-and-only.
That was until a photo came to light in an ebay advertisement which featured the same door treatment to an LD. This is now quite a different story. The cars are not the same car. So it appears that the Maxwell factory was possibly offering doors as a body option for the LD. There have been no examples of this treatment to any other model.
So, as the members of the MaxwellBriscoeOwner's Group are the best Maxwell researchers, I am throwing it open for comment.
This is a collaborative effort by David McCredie and Frank Cerutti in the interest of extending our knowledge about the Maxwell.
