This wooden scale model is based on the Colombo V12 engine used in the Ferrari 365 GTB/4 Daytona and is said to have been fabricated by Bill Dietz over a period of three years. The model is constructed from several variations of wood depicting the carburetors, intake trumpets, valve covers, cylinder heads, engine block, distributors, oil filter housings, and clutch assembly. This wooden V12 scale model is now offered in Thousand Oaks, California, with a display stand a protective cover.

The scale model was reportedly fabricated and assembled by Bill Dietz using multiple pieces of wood with varying finishes, cables, and wire joined together to resemble the V12 engine used in the Ferrari 365 GTB/4 Daytona. The model is said to be 1:1 in scale and measures approximately 36″ long by 22″ wide and 24″ tall with an estimated weight of fifty pounds. Details include an engine block, cylinder heads, a generator, and a water pump.

The model is topped with six sculpted carburetors along with velocity stacks and throttle linkages. The black-finished valve covers feature Ferrari-style branding.

Dual oil filter housings are mounted at the front of the model, while twin distributors and a scalloped wood block in the shape of a clutch pressure plate are secured at the rear. Decorative fasteners and clamps wear a contrasting finish and are shown up close in the gallery.

The piece is situated atop a black display stand with a protective cover, both of which are included in the sale.
