The CV345 disc seal triode was based on the VX3019. The TD03-10 has a 10 Watt dissipation that matches the CV354 specification.
The literature from the post war era gives the DET23 from M-OV and Mullard TD03-5 as equivalents but these two valves have a maximum of 5 Watt anode dissipation.
This physically small disc seal valve has co-axial connections. The heater and cathode are opposite the main envelope. The grid has a circular connection to the flat internal metal mesh. The anode appears to be copper and has a flat surface facing the grid.
A grounded grid configuration would allow for a two cavity mechanical design.
The grid is a set of fine wires stretched across a circular opening. The cathode and anode are both end in flat circles placed very close to the grid. The about page (top left logo on home page) has close-up images of the grid.
The planar envelope is 15 mm in diameter and, tip to tip is 60 mm tall.
