Some of the older Klingon model designs have been updated as they are rereleased. I can see that the Enterprise D would need that too.
Definitely the case that injection-moulded plastic models and miniatures have come up significantly in quality and down in cost in the past two decades as the technology has changed.
It would be important to know if these rereleases is an updated reissue or not. The proprietor of this shop seems to be in the k is on these points. It would be worth messaging him to ask if people are interested.
By the way, from the information he seems to have got at the con where the upcoming SNW Enterprise was promoted, it sounds like AMP is reworking the model design from its limited issue Discovery Enterprise to match the refit between Disco and SNW.
