Really looking forward to more progress pictures on your Greif, this is a mythical vehcile!
The joint between the lower and upper hull is tricky so make sure that you dry fit and sand away as necessary.
I built the Griffin panzer grey overall with the exterior overpainted in 70/30 dessert yellow.
Thanks ,I will make sure to test fit ive probably not worked on it for a good few years as it was sitting around my dads house [:I] But ive still got alot of 1/72-1/76 and 1/35 tanks and trucks on the way in the next couple of day and i will post what models arrive.
