This case arrived yesterday. It's a landspeeder-specific custom case for vintage boxes from CGA (the company behind AFA grading...ie, the same sources of cases for actual AFA graded items). I'm quite possibly going to grab a few others for my other vintage vehicle boxes at some point.
The only downside to this company is that they wouldn't declare the shipping cost at the checkout...just said they would bill it later (so I had it shipped to our US freight-forwarding address).
Saw this custom display case manufacturer at the Hobby Fair in Auckland yesterday. They can make case from small vehicle/12-inch figure size, all the way up to 2m tall floor-to-ceiling displays. Their prices were very reasonable.
