Atlas announced today two 40 foot ice reefers lettered for Producers Produce Springfield, MO. MFAX 110: https://shop.atlasrr.com/p-57584-n-40-wood-reefer-producers-produce-110.aspx MFAX 111: https://shop.atlasrr.com/p-57585-n-40-wood-reefer-producers-produce-111.aspx These cars might have lasted into the 1950s, but I don’t have any prototype information on the cars to back that up. Producers Produce was an MFA affiliated company, and had a facility on Main Street north of the Frisco Station in Springfield. The building was rail served off of Phelps Ave. I found this document that has some interesting information about the plant ( from a modeling perspective ) including floor plans ( not to scale, but it gives a good idea of the structures involved. ): https://images1.loopnet.com/d2/II53ekb0NBqxKLTNFuq01k1Z0gpW0oEpbnzRjh2P9sM/document.pdf Paul
Paul, the building diagrams are to scale. Look at the lower right of those pages. The scale is there.
