Thanks
I believe the Curteys are the ones now sold by 1st Corps - they have that tag in the 1st Corps webshop and are sometimes described as that on EBay. I’m not 100% sure though.
They are indeed the same figures. I should have checked your link beforehand.
They should sit fine alongside the Crusaer stuff. The sculpting is not to the same standard, but they paint up nicely. Some of the command figures make nice characters.
