1916 Simplex (Crane Model 5) — historical background
The Simplex Automobile Company was an American luxury manufacturer (Brass Era), formed in 1907 and producing high-end vehicles through the late 1910s. Simplex acquired Crane engineering advances in the mid-1910s, leading to the Simplex Crane Model 5 (often called Crane-Simplex). Common references cite an engine around 563 cu in and output around ~110 hp, with a long wheelbase around 143.5 inches.
Museum-grade takeaway: emphasize verification culture — “only ship what passes tests,” matching this Real-Build spec approach.

Museum display standards checklist (applied to LEGO)
• Clear identity plaque (model name, year, scale, piece count).
• Non-cropped documentation views (front/side/rear/top/3-quarter).
• QC checkpoints with “what to inspect” callouts.
• Provenance: what’s historical reference vs. interpretive LEGO choices.
