I built my Greyhound as fresh new kit together with M-20. I built them to serve as presentation kits for EXTRATECH company during Model hobby fair in Prague. Therefore I built them without any big modifications. I was also the first critic of these tow kits but I have to tell that all mistakes I have found reduce my positive tenet concerning these excellent kits for 10% max. The first problem I have found is little longer connection tube of front axle. I simply cat out part of it. Other problematic part is MG mounting ring that is little crooked. This problem solved hot water. The etched part that should be glued-on the resin MG mounting ring is for noting and I threw it away. On the other hand I missed parts that should fit the MG ring to turret pillars and I had to scratchbulit them but it was very simple. The rest of assembly works was simple and I enjoy it very much.
