It’s okay to ask for help locating a retailer for a kit. Squadron, Great Models and HLJ among others get name dropped a lot. They’re advertisers so that’s fine. It’s the use of the forum to sell or trade among members that’s frowned upon.
But I agree with Tankmaster; screaming like that when your original post hadn’t been up a day - take a deep breath friend. I know it’s a cool looking space plane, but a simple “bump” post will suffice.
Now to answer the original question - I have seen this kit on eBay on occasion. Just have to be patient.
