Privately owned and photographed in September of 2017 at the ODHFS Farmville, Virginia muster is Chesterfield County, Virginia Engine 24. It is a 1970 Duplex/Oren "Guardian" 1500/500 with serial number 2746.
This was one of two 1970 Duplex/Oren's delivered to Chesterfield County. Engine 24 has a Detroit 8V-71 with an Allison automatic transmission. The second Oren, Unit 34 from Bensley, had a Cummins engine and a 5 speed transmission, also a 1500/500. These were the first yellow engines in Chesterfield County.
After service at Chesterfield County, this Oren was sold to E.L. Dupont Co. for their Martinsville, Virginia plant. Dupont donated the Oren in 1998 after their Martinsville plant closed - donated to the Henry VFD in Franklin County, Virginia. It was sold to a collector in 2009.
