These two are embossed on the dome: P.R.R. and B on the skirt. The left one has a nice uniform color. The three vent spikes on the inner skirt are flaked off. Minor inner skirt flaking. $7 plus shipping. The right one has very thin olive streaking in the skirt and up into the dome. See the skirt area to the right of the B. Not sure if this one had vent spikes or not. VVNM. $8 plus shipping. (One more pair of these to follow!)
