The weapon kill banner from the previous arm was re-mounted on the new arm using some small 2mm magnets.
To fit the power cables a small raising of the sockets was needed, I converted these from the elbow joints not needed for newer titans like the Warbringer Nemesis.
I added the heat staining to the muzzles using washes - Nuln, Drakenhoff Nightshade, Hormagaunt Purple and Seraphim Sepia.
The rear Mechanicus cog motif was painted and an Astorum sigil added to the centre.
