Markings on the valve are:
CV155, which appears to be on top of CV55
35/60 and 36085W (and 31/72 and 21900W on the second example)
JMC on the glass.
The 35/60 (see the picture at the bottom of this page) indicates the peak emission current (35A) and the cathode current (60mA) at Va=100 and Vg=0. The second valve is marked 31/72 (31A and 72mA)
