Unidentified Undead Command figure

I bought these 3 Citadel Undead command figures off eBay in January 2020, I know the two on the right (skeleton standard bearer and musician with horn) are Citadel 4th Edition Undeaded figures from the early 1990s but I can't find any information on the one on the left.   He looks to be a skeleton command figure in armour, possibly 3rd or 4th edition (1985-1993?). Even looking on the Stuff of Legends webpage that has a very good listing of Citadel / Marauder figures did not help.

Wish to identify the figure on the left.  
They have all been stripped of paint and are ready to be repainted

It would be helpful to see a picture of it painted from the time period as it is not clear to me if the hands are bone or rotting flesh.  In the above picture the painter has opted for rotting flesh.

More pictures below.

Invasion of the Dinosaurs

One of the Doctor Who scenarios I wish to run is Invastion of the Dinosaurs featuring the Third Doctor.  I have started acquiring and painting various Dinosaurs, and of course I have the third Doctor.

Looking for a leader figure for my Skeleton scythe warriors

I think one of these three Citadel C17 figures will work as a leader for my Grim Reapers company.
