Absolutely! WP 753 was assigned to the SN early in the 1950s in the Zephyr scheme. In June 1953 the car was formally transferred to the SN, renumbered 1627 and was occasionally photographed at around Yuba City. It remained in the Zephyr paint until retired, officially in December 1958, though it might have been out of service even before then. I don't have the documentation anymore, but IIRC through some dodgy number swapping with another retired car in really poor condition held for donation at WP's Sacramento Shops, SN 1627 was sent to Travel Town at Griffith Park in Los Angeles. It remains there to this day as a WP car.

Also take note of the even rarer all-orange WP 787. This car also came to the SN in May 1953 and was renumbered 1626 without repainting. It too served out of Yuba City, wearing orange paint until retired in December 1958.

Photos of both cars at Yuba City in the 1950s are found in Jim Eager's WESTERN PACIFIC COLOR GUIDE TO FREIGHT AND PASSENGER EQUIPMENT, page 120. They are typical Haskell & Barker cars; in fact 1626 was built by H&B in 1910. 1626 was part of a small group built by WP to the same plans in 1924, except it had a steel center sill as original equipment.?

I have a photo of both cars at YC in my collection, and also two views of WP 753 at Live Oak. My apologies, but I do not have permission to share them.

And I want to say here loud and clear that these are NOT "Gould Standard" cars. Unlike "Harriman Standard", there never was such a designation for common designs on Gould roads. However, the D&RGW and the MP both had cabooses built to the same design.?
