Hi Cris,
The Mullard MW36-44 employs a pentode gun assembly whereas the MW36-24 has a tetrode gun. The tubes are interchangable, the only difference is that pin 11 (anode2) of the MW36-44 can be connected to the cathode or ground to provide a degree of pre-focusing.

The MW36-24 was fitted into many Pye V4 sets.
