A wee addendum. I bought some Tamiya uniform insignia decals, in 1/35th
and , importantly, 1/16th scale.
These are the details:
I decided to give them a try by using the epaulettes/shoulder boards, and lapel badges, specifically made for tank crew. There's no way I could have painted those details so finely. Anyway, the decals are fairly easy to use, and made easier when applied with a coat Humbrol "decalfix' beforehand. I gave the Commander the rank of Hauptmann/Captain.
All that remains to be done with him (no, not being tossed in the bin

), is to paint over the home concocted pink piping I'd created, and which now adds an unwanted fringe to the Tamiya add-ons. My apologies, as the dust that landed on the Hauptmann from a spot of internal sanding on the Firefly, make him look as if he needs his dandruff treating with 'Head & Shoulders'. (Kopf und Schultern)
All in all, I'd say the decals are worth investing in. I got them from eBay.
