1927 Holt trailer is up for sale on Bring a Trailer... no reserve, and it's only at 8400. But it's immaculately restored, a real museum piece that's been in the Petersen, and has called the Murphy home for the last 5 years

The prototype was stored and remained in the ownership of Mr. Holt’s family through 2009 when it was acquired by a vintage travel trailer collector. It was then refurbished and displayed as part of a private museum in Santa Cruz, California, and was also briefly loaned to the Peterson Automotive Museum in Los Angeles. It was finally donated to the Murphy Auto Museum in 2019.

1927 Pontiac running gear consisting of the axle, leaf springs, and wood-spoke wheels.
