Have a search on eBay (or possibly charity shops) for Austin Powers figures which are a nominal 9 inches in height giving you (if my maths is correct) a 6 foot tall figure and the limbs are adjustable. One of my future models, still very much in the planning stage, will be an amphibious vehicle and due to the wheels/tyres available to me works out to be a scale of 1:8 so will just have to get either my wife or daughter to dress Mr Powers an an American G.I.

I used a dolls house man here:https://www.melodyjane.com/dolls-house-people/dolls-house-men/dolls-house-people-smart-victorian-gentleman-miniature-resin-figure

Look for the Victorian Gentleman.

Then I cut off his right hand and glued it back on with palm facing inwards so that he can grip the wheel.

Lastly I cut the back of his legs off and the bottom of his tail-coat so that he is leaning back against the seat.

Using Fymo clay I made a life jacket and a jaunty sailors cap.

The passenger is from the same series and is “seated lady”

Just add a headscarfe and a lifejacket.

Those figures work well if your model looks appropriate as 1/12th scale.  The Borkum is supposed to be 1/10th but it’s close enough for these.  They are defenately a Summer trip though as there’s not a coat in sight on my passengers!

I can see the Seated Lady from Melody Jane in the “Borkum”

I dont know the scale of my Huntsman. Its a loft find.

The length is 34″ and not the 46 1/2″ version.

For the larger one I simply used Action Man size figures from a charity shop.

Its a Precedent from about 1970 – 80

I would say that the accesories guide was done on a typewriter.
