Anyone know if they make any of these models? I know GW did that armor through the ages pack but it doesnt seem reasonable to buy a ton of those to get the armor type down. I have been reading the Horus Heresy books and eally like the way the armor and wepons are described in it.

Nope, if you want a full pre-heresy army its all conversion work.

Here is a link to a pre-heresy style forum. You can find links to how to make heresy style armor and such.

The Great Crusade

Also Bell of Lost Souls has heresy transfer sheets you can print out.
Dig around there is a TON of stuff pertaining to making armies in this style.

Thank you sir

Yeah, it is alot of conversion, bolter and chainsword pre-heresy bits guide helped me out alot, alot of those bits you need are already out there kicking around, take a look.
