Here goes a long term project. A page a day from the whole range of Citadel catalogues, from the 1980 Red catalogue up to the 2010 world catalogue with all the various spin-offs in between. Not going to do them in order, just whatever inspires me or seems relevant at the time.
So we kick off with the first page of the 1991 BLUE catalgogue entitled "MARINE COMMANDERS". The 2 Imperial commanders at the top of the page are of course Leman Russ himself along with his wolf companions Freki & Geri (who have lost their names and now been referred to merely as 'wolf kin' by Forgeworld ) and Marneus Calgar, here listed as Lord Macragge (Ultra Marine Commander). Even in this first incarnation Calgar is still seen with the gauntlets which he is modelled with to this day. Both commanders sculpted by the amazing Michael Perry. At this early point its worth noting that the Citadel designers considered Primarchs to be the same physical size as other marines.
The second half of the page is a collection of 6 Captains by the masterful Jes Goodwin. 4 of which are modelled as being from specific chapters and 2 generic. We can of course see here an as yet unnamed Captain Tycho as the Blood Angel sculpt. Its interesting to note that these early captain helmet designs would find their way into much later boxsets, the Space Wolf 'Wolfs head' design which was in the Space Wolf plastic multi part boxset and the plumed helmet on the Ultra Marine which is seen frequently on Forgeworlds 30k Marine range.
