The 30th Anniversary model is based on the original Space Marine model, with his pre-Bolter combi-weapon and circular plate on the shoulder.
Check out the cool modern-era bayonet BTW.
The model will be around $50 AUD/ $30 US or free if you spend some large amount of money - probably around $160 US...or $14,000 AUD! :(
Quite a bit for one model - which is a shame - as we could have recreated this scene (right) from Rogue Trader with the first scratchbuilt Land Raider
