I just got two of these -- one in the white plastic, the other in brass mat steel. Excellent, excellent work on the design! Even the ventral surface has the correct details, and the whole thing has a nice weighty feel to it! I will be buying more in the future to give away as gifts! This has to be the best trilobite model that I have seen anywhere, and I shared the link with the Trilobites Group on facebook. Thank you dadrummond!
