All of those photos are of R-40-10 reefers. The BR-40-10s were dark green with yellow/orange (probably Dulux) lettering and no herald.
There’s a colour photo in the article I mentioned in your other thread (April 1987 issue of RMC) - I can scan it, but don’t have permission to post it here.
There is a BR-40-10 listed in Bob’s photo list but it doesn’t specify if it’s in colour or b&w.
The green is not Pullman green but an olive green unique to SP & PFE, No CS charts for this color remain, so i’ve arrived at a formula based upon several surviving sources, comprised of Pullman green with a couple drops of roof brown. Olive should be applied to the sides, ends and roof. Trucks, underframe and hardware were black. Lettering is deluxe gold with no heralds.
As built, the 50ft express reefers had no roof hatch platforms, displayed indvidule grab irons on the sides and ends with high mounted Minor brake wheels, boasted no end lettering, classification or PFE ownership data and wore a coat of dark olive/brown on the truck frames, they were lettered in gold leaf for Wells Fargo Express or Western Railway Express both of whom were later merged into the Railway Express Agency.
Thanks to you I have contacted the library of California State Railroad Museum and the Librarian Cara Randall has photograph copies, for sale, of the P.F.E. BR-40-10 Express Reefer car.
Also, I will look into the Volume II book, of the P.F.E. Reefers, which you mentioned.
