I see from the link Marc Brandes provided that Meng has 4 zimmmerit patterns for their late model Panther A but has no illustration of the after market zimmerit "decals" MENG is offering.
According to "Panther External Appearance and Design Changes" by MacDougall & Block, Panther Ausf. A was produced by the firms of M A N, Daimler-Benz, Demag and M.N.H. Each builder applied a distinctive zimmerit pattern to the vehicles it produced. Until MENG offers illustrations of its decals, a modeler cannot tell which of the four zimmerit patterns will match the pattern of a particular vehicle that is the basis of the model. I would hope MENG will not continue to refer to Zimmerit patterns A, B, C and D but would list the factory that applied the zimmerit pattern, M A N, Demag, Daimler-Benz or M.N.H. Until MENG either lists the factory that applied the zimmerit, or at least provides an image of each of the zimmerit patterns it is offering, those of us building a particular Panther A will be limited to applying a home made zimmerit pattern or using the other after market zimmerit applications like that produced by Alkelt (the M A N "tile" or anti spall zimmerit pattern).
Thanks for the heads up Marc but it seems like we'll have to wait for more information from MENG before we know which zimmerit product we're going to buy.
