This viewfinder tube was made as a specific part for a camcorder and does not carry any identification. These special tubes often were left without identification. Like all such viewfinder tubes the quality of the engineering is superb and they are capable of displaying a high resolution TV picture.
The two diameter neck is designed so that the deflection coils can be wound directly onto the glass.
