I purchased T-Rex Studio TR85056 (King Tiger Tracks 18 Teeth Late Type), which used Przemek Wojdas’s 3D drawings, via fleabay for about thirty bucks plus $3.00 shipping.Excellent product EXCEPT that they are incorrect for a final production (March '45) KT. What you get is approximately 250 right-handed Kgs 73/800/152 links. You can’t place them on the single link hangers on the final KT turret because the studs, using Hilary Doyle’s drawings as reference, don’t align with the appropriate cutout on the link. The hanger/studs are located specifically for the left-handed links which were flipped over for use on the right side of the tank. I’ve complained ( more like whined 
) about this for years. This article corroborated what I’ve been saying all along. I contacted Przemek about this; and, he indicated that he will be printing a corrected Panzerwerk Design set.
