Took me a while to find this guy as he was sculpted long after the original Scouts! He’s part number 99060101301 and can be found in the 2005 US catalogue on page 229.
A 2004 sculpt.
This guy is part number 070270/1 and can be seen on the Armour Variants page in the 1991 Blue catalogue. He’s shown in White Dwarf 123 (March 1990) as “Urban Camouflage Imperial Fist Marine in Armour Variant”:
The details on the base have been filed off, unfortunately.
Colours used:
Here’s an early attempt at a paint scheme for an Armiger/Moirax from 2020-2021.
The Volkite glow done as red was a mistake – it’s too close to the base and not glowy enough!
This guy is part number 99060101413.
