Nice work - just want to tell that the position of the bipod in your No-1 figure of the MG 42 is technically not possible due to a spring mechanism. If you fold it down it has to clip into the housing of the barrel by two small metal tongues on the backside of the legs of the bipod. Otherwise it is fully open and locked into the upright position. I know that John Rosengrant was showing his original in the same way.
As said - very nice results!
Cheers, Martin
