There was some discussion on this subject at
https://www.modelboatmayhem.co.uk/forum/index.php/topic,57045.msg593443.html#msg593443I obtained some plans from NMM and recently completed a model in 1/32nd which hopefully will appear as an article in Model boats soon. All my best pictures are with MB editor but hopefully this one gives an idea.
The Deans version in 1/24th seems to be based on the picture of the two boats during trials on the Thames and has interpreted the engine compartment as a cabin with a forward facing window. I hope they eventually get round to some dedicated crew figures matched to manning the various positions as probably the trickiest aspect of the model was cobbling bits of various plastic figures together to arrive at a crew in the right uniform and realistic poses
