Your picture of the tube layout shows 21fjp22, which has a bonded glass. It should be frosted. Also common during this period is the 21fbp22, which is the same tube without the safety glass. They usually have a dark tinted, curved safety glass laid on the front of the tube with a black rubber or vinyl gasket. It looks lust like the front of the tube when installed, but isnt frosted.
