My current plan is to build a model of this car from scratch using wood and styrene. I initially started building it in February 2020, but I just wasn't happy with the results. My current, renewed effort is to first design it fully in a CAD program, so that the whole thing is planned out.

In S-scale, SouthWind Models imported two versions of this cabin car, one with a centered cupola, and one with an offset one. Omnicon Scale Models made a model of the 2B1F2 arch bar (leaf spring) truck sideframes (these were flagged as freight trucks).
