The initial releases were divided between c26 Lizardmen and C27 Lesser Lizardmen. A new set of sculpts was released as C19 in 1984, and slotta versions in 1985. Very few of the 1984 or 1985 variants ever appeared in catalogues.
The full range of the solid based C19 Lizardmen can seen on the CCMWiki here.
