I'm thinking to build a small diorama, let's say H0 scale (1/87), dedicated to the Doctor & Companion. So I've started building the TARDIS that you can see in the picture on the left, still not completed. I'm building the master parts by styrene sheets, and molding them with resin.
At my preferred scale model shop I've found out three railway figures, actually showing a saluting man and a woman with their young kid (that i've removed yet in the pic on the left), all fitting their '50 mood clothes. I think that with a few modifications on their clothes they could play a believable doctor & companion.
