Holy moly, that Packard Bell is a gem! You should contact the Early Television Foundation that it may be counted it in their database.

You are very close!

Remember in the mid 1950's, they still measured the glass (or metal) envelope and not the viewable screen itself until the US government required that the measurement to be the viewable portion.

For instance, per RCA's 1957 spec sheet, on the original 21CYP22 that the Ampico-Kid mentioned on his 1959 Caufield, the outside envelope measures 20 and 13/16ths inch with a tolerance of + or - 1/8th inch. (The outside glass had to be over 20.5 to be counted as a 21 inch.)

The usable image area is 15 and 1/2 inch high and 19 and 1/4 inch wide, and since it is round, the actual diagonal is also 19 and 1/4 inch.

If this were compared in size to a rectangular image in modern diagonal width measurement this equals:

(15.5 squared) plus (19.25 squared) = square root of total

or just a smidgen over 24 and 1/2 inches diagonal, if it were a rectangle.

Hope this simplifies things.

A restored and working second version CTC 7 Grenoble with remote from 1959 and the 1961 CTC 10 Monticello as yet unrestored. I'll work on getting some better screen shots.

I just marvel...The folks in antebellum 1959 NEVER thought that their products MIGHT be obsolete in 2012..And didn't CARE if they were...They went ahead & did their damndest...And their products can still be viable 50-odd years later...Contrast that to today...All sorts of stories of DLP tVs losing their lights after 3. 4, 5, yrs of use...And they cost a king's ransom compared to the color overachievers of 1959...Shameful. This era impresses me NOT AT ALL...Except for its unrelenting CRAVENNESS, making everything cheaper & cheaper, NOT Better & Better...Or am i being a reactionary, backwards, inbred Redneck Old Poop, as usual ?!?

HD (as we know it today) didn't exist back then, things are different now. Besides, we on this board make up for the fact that we watch modern sets by restoring the old ones. In that way, we hope to make up for the shame of watching modern plastic sets! lol

Guess you'll have to settle for these screenshots for now. One of these photos is not like the others:

That's my CTC-5 Whitby, proof that anybody can bring one back to life given enough time! More later...

Vanna never looked so good as on that CTC-5 of Ralph's.

1956 Raytheon C-21C1M

WOW!!! another one that probably needs to be entered into the ETF database.

Hard acts to follow
 

Such wonderful sets everyone! The PB and Raytheon are very interesting!

Here is my contribution, though a bit newer. Have had the CTC12A Burgoyne since 1979, the CTC11 Wakely since 1986. I lost many others during many moves...:sigh: before VK I had no idea anyone cared about these but me..

1955 Hoffman M4021A

Some incredible resolution from the '57 and '58 sets above. Some claim that the older the color set, the better the color rendering... but I remember the picture on my 1967 CTC-24A "Glenview" being far superior to anything that came out in the '50s... (when my set was still working, that is). I remember its excellent convergence (little to no stray color on B&W) and sharp focus.

Theremin, do you have a photo showing more of that room? I get the idea there are other interesting TVs on display (for instance, I spy the edge of a DuMont RA-103 in the Revere cabinet).
