I have no direct knowledge on these early color prototypes, but as a general observation lab prototypes are considerably different from field test sets. Field test sets like my RR359's were built more like production units since they were placed in peoples houses and had to be robust. There were also 100 of them built, so they needed to be assembled more like a regular production unit. There are little differences in build quality between them and production units.
Lab prototypes like this set that were never meant to be taken outside the lab, built on the order of 1, 2 or 3 units, and not operated by anyone but engineers usually lack the build quality of field test sets. I have a prototype pre-war GE set that has no mounting flanges on the chassis or mounting holes in the cabinet, nor any evidence that it ever had a back. This was probably done as the engineers would have never bothered bolting the chassis in anyway, so why bother. They were typically housed in decent cabinets so they could take the "glamour" shots to be used when documenting and displaying the sets to licensees and the FCC.

Just my 2 cents.
