I have had Revell come to my assistance twice - one time a clear frame was
missing, and in a week I had one delivered, and another time I asked for the
possibility to buy a clear frame for another kit to do some conversion, and
I got one for free in less than a week. Just superb service.
Both of those were direct to Revell in Germany, but recently I had a
replacement frame for my Trumpeter P-38L from The danish agent, it took a
little longer, but I got it without any trouble. (Upper wing poor casting
outside the left engine in the flap area). Also a good service from the shop
Vest Jysk Hobby and agent Danmore Hobby.
