Mirco Pecorari, the talented designer and 3D artist behind the Hall Bulldog’s digital reconstruction, has published a dedicated page on his personal website showcasing his work on The Hall Bulldog Project. You can view it at mircopecorari.com/projects/hall-bulldog.

Aviation Archaeology

Mirco describes the project beautifully as “aviation archaeology” — and that’s exactly what it was. No complete technical drawings of the original 1932 Hall Bulldog existed. The only references available were vintage photographs, often distorted by lens effects and incomplete in their coverage. Mirco’s challenge was to extract precise geometry from these imperfect sources.

As he puts it on the page:

The Hall Bulldog project is not a replica. It is a reconstruction of geometry through discipline — a bridge between fragmented history and structural truth.

The Method

Mirco’s page walks through the systematic process he used to create the 3D model. The workflow began with rigorous photographic analysis — isolating distortion-free areas of historical images to reconstruct accurate 2D three-views, which then evolved into a precise 3D model. Each photograph was treated as a calibrated lens, with virtual 3D cameras matched to archival images and parameters adjusted until geometry aligned.

The process was iterative and disciplined: modeling, camera matching, correction, refinement, and validation. It took fifteen full iterations to achieve a coherent match between the digital reconstruction and the photographic archive. Those iterations are documented in detail in Mirco’s design reports.

A Methodological Statement

What makes Mirco’s page particularly compelling is his framing of the project as a methodological statement. He writes:

Between a faded photograph and a steel tube structure, there can be a bridge. That bridge is built with discipline, intuition, and iteration. When the proportions finally align, it is not nostalgia. It is geometry restored to life.
