Vehicle Details
AI Listing Summary
This 1909 Simplex 50 HP, chassis 5009325, is a rare and historically significant automobile with a continuous provenance and original coachwork by Holbrook-Singer. Having participated in numerous Glidden and Transcontinental Tours, and with notable former owners, it presents a unique opportunity for collectors seeking a well-preserved, museum-grade example, despite needing recommissioning after a period of mechanical dormancy.
Condition
7
The car is described as mechanically dormant in recent years and awaiting sympathetic recommissioning, but it retains its original Holbrook-Singer Toy-Tonneau coachwork and is considered a highly authentic, tour-proven machine. This suggests it's in solid condition overall but needs some work to be fully operational.
