All the details I got for this figure came from the Colonial Marines Technical Handbook
printed about a year before.
I didn't get it all right, just as much as my meager skills would allow at the time.
The original figure was milliput then cast in G26 resin as a master for casting.
The pulse rifle and other gear was scratch built from plasticard or perspex,
then cast in resin or pewter depending on what it was.
The pulse rifle was moulded with the hand attached.
