Great time line developing here for these manuals. Be curious to see if by the time Bruce Parker's edition hit the presses, what, if any, references were made in it to the Mk I Set. Would not surprise me if the Mk I was rapidly being withdrawn from service. No mention at all of the Mk I by the time the RCA Mk III Canadian manuals came out.
Based on Bruce MacMillan's manuals, it would appear Philco (P.C.) may have been the prime, initial US maker of the 19-Set Mk II and was responsible for all subsequent publication of the Working Instructions. I think RCA ended up in that position this side of the border, regardless of who actually made the Mk III sets.
