@Gatlag:

I've gone through my bitz box and found quite a few heads that might be useful...
Cadian Command Squad (have spare of both of these)
Cadian Command Squad Officer Peak Cap (have 3 of these - how many did you want?)
Catachan Command Squad Soft Cap (have a spare one)
I also have the 'emperor' bretonnian knight head that you have pictured

I came across a few others you might fine useful: 2 blood angel sanguinary guard heads, 2 of the old sentinel driver heads - with soft flight helmets and the cadian soft cap head with the visor and mini com (3 of these) - Any use?

PM me if you're interested and so I know where to send them!
