This isn't eBay related; I dealt directly with the AFV Models. I did get a response from Axel @ AFV today. He seemed as amazed as I was, and was very apologetic. He offered to ship the missing elements immediately. I responded politely asking that he send them faster than the previous parcel, so we'll see what happens. At this point, it is starting to look like an honest mistake, which is understandable. It is just painful when there is a 3-week wait for deliveries!

Thanks for your offers of help. I'll keep you posted on this!
