Conquest Miniatures (not to be confused with Conquest Games!) seem to have disappeared. Their website is defunct and I can't find any sign of a new one.
However, they had a distribution deal with Warlord Games who still list the Conquest figures on their website.
As far as I'm aware, Conquest was a one-man-band operation. So maybe he has sold the rights to the figures to Warlord, or maybe just sole distribution rights?
If anyone has any further information perhaps they could let me know!
Looking for 28mm historical miniature figures? This blog is a database of manufacturers showing who makes what. I am also adding photos showing figures from different makers side by side. The 'Directory' tab has a list of manufacturers showing what ranges they make and a link to their website. The other tabs list what figures are available for that period.
