The seller collected these parts over the past two decades while completing several restoration projects, most recently a Mercedes-Benz 540 K Special Roadster. The collection includes mechanical, interior, exterior, and trim components. A mix of period and reproduction pieces is included. The collection is offered at no reserve in Harvard, Massachusetts.

Custom components are included that, when assembled and finished, replicate the appearance of an original fuel pump while concealing a modern fuel pump.

Reproduction rubber profiles modeled after components removed from a car are included. According to the seller, dimensional drawings and PDF files will be provided to the winning bidder.

Pistons and connecting rods are attached to the crankshaft.

More than 175 photos documenting the collection are included in the gallery.
