Is this CRT from the 1930's?
Seller says it is. I doubt it, since television here only began in 1950. According to him it is a Sylvania codes 7GP4,7JP4 .

It's 350 in Brazilian currency.. which, converted to US currency, is something like... 175 dollars... still, a lot of money.
This people on the Internet auction sites ( both here and abroad ) are really funny. Just because they have something that is quite old, they immediately assume it's older than it really is, and that it is worth much more than what it is really worth. Unfortunately ( for them ) the Internet made their life more difficult. If this guy appeared with this CRT on an antique fair on the street in 1990, he most likely would be succesful on selling it for what he is asking for, if not for even more. But today... you see, just in a very few hours I got the correct information about this CRT.

About 12 years ago, I rescued a little old CRT from the "free" pile at a garage sale. I knew little about TVs at the time, but just didn't want them to throw it away. The type number -- 5TP4 -- meant nothing to me. I later learned that 5TP4 CRTs are in demand by collectors of 1940s projection TVs. I ultimately traded that CRT for a complete television. Phil Nelson

The ad says 7GP4/7JP4. 7GP4s were used in a few sets before the 7J came out, and are hard to find. If this is a 7G, it may be worth $175.

***EDIT - obviously you mean Bazil! ***
By "here" do you mean the USA? If so, then GE station WRGB in Schenectady, NY, broadcast TV for the entire length of WWII. "The initial home television reception over the air took place in Alexanderson's home in 1927, but the first public demonstration and WRGB's birth date was January 13, 1928 as the first experimental television program was broadcast and shown in Dr. Alexanderson's home at 1132 Adams Road in Schenectady, New York."  "Although WRGB telecast scores of "experimental" programs between 1928 and 1939, from a small 12-foot square studio, a more complete and regular schedule began November 6, 1939, generally thought to be the benchmark date for the beginning of modern television. A few years later, when the attack on Pearl Harbor closed down live, talent-produced shows at many other television studios, WRGB continued to operate off a full schedule." http://www.cbs6albany.com/sections/wrgb/history/ I grew up watching that station - beginning in the late 40's - so it's sort of near and dear to my TV heart.

Obviously that I meant Brazil.
I am perfectly aware of the starting date of television in the USA. Hell, I am so much a fanatic for television History that I can say by memory the starting dates of TV broadcasting in many countries of the world.

Of course I will let you know! TV broadcasting in Canada began in 1952
(see http://en.wikipedia.org/wiki/Television_in_Canada). The NTSC system is used, with the same frequency plan as in the neighbouring U.S.A. In fact, it appears that TV receiver manufacturing in Canada began in 1950 or even a bit earlier as U.S. stations could be received in many areas of this country. Good night Captain Video!

All right! Thanks!!! Now I know another date!!!
I have to make a little correction on what I have written above: I wrote that TV in East Germany began in 1952. Actually, I meant West Germany, but, being a non-native English speaker ( meaning that I am a not a citizen of an English-speaking nation ) I made a little confusion between "East" and "West" ... oh, well... Anyway, If I am not mistaken, I believe TV in East Germany began in 1952 as well as in West Germany.
