Just finished my favorite early armor - T1 HMC in 1/72.

Kit is very simple and contains only four parts - hull, gun and tracks.

CAD looks nice. Can you provide actual photos of model? Unbuilt and built-up? Not pointing fingers, but sometimes the product isn't as good as the CAD representation.

I should have suggested primered, too. (Asking a lot here! ) The semi-transparent material Shapeways uses for printing doesn't show surface detail very well. Also a primered model will show up any excessive printing lines.

I'm going to post photos of printed models just after get mine.

To imagine how printed models looks, here are the photos of unprimered and primered 1/200 Short Sperrin in the FUD material.

Be sure, surface details look good enough.
