Well, Revell was no help at all - so I guess I'll be buying a full kit.
Funny - Revell USA said, "Sorry, it's a German kit. Contact them, and tell them we told you to contact them." So I did. Then, a week goes by, and I get an email from the same lady at Revell USA saying, "Sorry, we don't have those parts - it's a German kit" and below this email was my original email to Revell Germany. *sigh*
So I point out that she asked me specifically to email them, and she replies, "Well, we don't stock those parts, and Revell Germany forwarded your request to us since you're a US resident."
Hmmm. I don't even want to go pointing out all the basic problems with this exchange to her, so I guess I'm buying the whole kit. However, I do know some folks who live in Germany....
