Duesenberg SJ Speedster 1933 — Ivory Display Model

OVERVIEW
This Duesenberg SJ Speedster classic open-top car is offered as an assembled display project. The inspected scene includes the complete source body, four wheels, open cabin with seats, windscreen, mirrors, grille, horns, lamps, bumpers and trim. Its presentation retains a proposed ivory body finish, brown cabin surfaces, black wheels tyres and chassis, bright metallic grille bumpers lamps and trim, and reflective glazing. The cover shows a proposed completed miniature display; it is not a photograph of a physical print produced or tested by the publisher.

COLOUR AND SOURCE APPEARANCE
The source has one default material. Proposed finishes are assigned to existing named body, metal, plastic, glass, chassis and wheel objects. No parts are reshaped, moved or generated. Vertex data, polygon connectivity and world matrices are compared before and after painting. The palette is proposed; factory colours and physical scale are not certified. No manufacturer endorsement or real-world functional specification is claimed. Existing surface detail is retained; source markings may be simplified in the compact colour viewing copy.

DOWNLOAD CONTENTS
The ZIP includes the editable FBX surface scene and supplied OBJ alternatives, the available associated texture when present, the full-resolution upright coloured 3MF, an English preparation guide, a file inventory and the locally generated presentation image. Geometry, UV coordinates and material assignments are checked after reopening the FBX in Blender. Absent optional bitmaps are not invented. The image replaces the earlier reference photograph. The manifest lists only the supplied files, their sizes and their current integrity hashes.

COLOUR VIEWING COPY
A separate upright 3MF contains 1,874,067 triangles from 108 inspected surface mesh objects. Triangle connectivity and coordinates are checked after export without surface decimation. A compact per-triangle colour palette approximates the presentation materials. Texture lettering, transparency and complex native shading are not reproduced exactly in that palette. The editable FBX and available texture resources are included in the ZIP. Maximum span is normalized uniformly to 150 mm solely for viewing. This is not a verified source scale or a certified fabrication dimension. Scene objects are not equivalent to printable part counts.

GEOMETRY AND ASSEMBLY
The illustrated arrangement is assembled for display. It does not establish that every surface is watertight, independently printable, detachable or mechanically functional. Check windscreen edges, grille slats, horn openings, mirrors, thin bumpers, wheel details and narrow trim. Imported meshes can contain open boundaries, overlapping surfaces, disconnected small features and walls unsuitable for a given printer. Repair, thicken or separate a working copy where necessary; retain the originals as references. No physical print, fit, structural strength, rolling mechanism or articulated motion has been tested.

Prepared for display and download. No physical print has been certified.
