Definitely custom bodied. Harley Earl was the manager of the Don Lee Cadillac Custom Body Shop during this period. They had a good market selling custom bodied Cadillac to the Hollywood elite.

Below is a list of the 1924 Cadillac prices. Notice that the Touring car was the lowest priced (adding the roof probably added a few hundred). Today we could probably buy that with pocket change.

Style No. Body Type Seating Price Weight
NA 4-dr Touring 7 $3085 1945 kg
NA 4-dr. Phaeton 4 $3085 1909 kg

5470 4-dr. Sedan 7 $3585 2095 kg
5300 4-dr. Limousine 7 $4600 2109 kg
5370 4-dr. Twn. Brougham 7 $4600 2059 kg

My guess is that this gorgeous vehicle is a Town Brougham model.

Usually the Brougham has a half roof leaving the driver in the sun or rain. (Same proportions in the rear as this).

This variation seems to have opted for a full roof.

There is no such body style as a full roof Brougham in the 1924 Cadillac advertisements. But clearly you could special order one because here it is.

[This is a touring car with what was generally known as a "California top," an aftermarket or dealer-installed accessory that was a cheaper alternative to a closed car. - Dave]

This Cadillac, probably a Type V 63 touring car, has an accessory fixed, but removable, hardtop. They were developed and popularized by Murphy Coachworks in Pasadena, California. They became generically known as "California Tops" regardless of by whom or where they were made

Who knew there was Cadillac 4-door hardtop before 1956? Very interesting, I wonder if that was factory or custom bodied.
