That mask looks like it was cut from a single piece of wood, so they probably ruined the original in their first attempt. (If you ever tried to use a router on something like this, you will know why.) You also can see a new joint in the side of the cover. Frankly the conversion would have looked better had they just blackened the mask.

Another thing noticed, is those knobs look like they belong to a "blonde" (RCA called it "Toasted Mahogany") set or they were spray painted.

I've never seen an original RCA knob of that era discolor like that.

Yes, those knobs are from a "toasted mahogany" 621. The funny thing is I've never seen a restored blonde model with these proper painted knobs! They usually use typical dark knobs which look terrible against the light finish.
I still believe there was an after market service to make these early TV masks "double-D" style. I've seen them done very well. An example is the RCA 8TS30 which looks factory, but is not. I can't picture owners doing this themselves:
