That sounds like a CME1703. The number "2" is probably a garble of one of the other characters. Be aware that this has a 12.6V heater, rather than the more common 6.3V. It's still 300mA so will work in a standard 300mA heater chain. The different voltage will make little difference but it's worth checking the voltage across the heater when it's in the set just to be sure. Then if you test it outside the set, you will know what heater voltage to use.
It can be replaced with the Mullard AW43-88 which has a 6.3V heater. There are many other near equivalents.
What really mattes is how it works in the set. If you get a bright picture then there's no point in testing the CRT.
