From the post:
We have been working with the manufacturer to ensure we get the highest level of detail without compromising the feel and robustness of the models. The latest samples we have received are much closer to meeting the high demands we all have. We are really pleased with how these hold up against their metal counterparts, the level of detail is quite stunning. Please note these have not been finalised yet, we have a few minor improvements we are requesting, we look forward to sharing the final products soon.
