Thanks for all your advice on this. I knew there must be one somewhere, but a previous owner had replaced the floor panels and also fabricated a new gearbox cover but the floor obscured the filler plug. I have now found this and have made a little space on the edge of the floor so I can get a filler...

I am trying to check the oil in my 1935 10 Litchfield, but there is no sign of a filler plug nor a level plug. All I can see is the drain plug. I vaguely recall when this went into my local garage for an oil change they had to pump oil in through the drain plug until it reached the level of the tube...
