The hull has now had a few laps of primer, filling, sanding, primer, etc. and the colour coat can go on. Nice. I've chosen to try and replicate the real-life ST 1502 which, rather helpfully, is quite local to me in Portsmouth - I might have to go and see her one day.

And while the painting progresses slowly, I can get the numbers and roundels cut from vinyl using the 3D printer (see my other project). The typeface is one I found on the web that's a close match to the photos of ST 1502 (post refurbishment), which I then tweaked a bit in Inkscape.
