I've added all the markings now, and faded the paintwork to give it a worn look. I've added some kill rings to the barrel end;

I attempted to create stencils for the turret numbers, but they didn't come out well after painting. I had to go over them and clean them up by hand. I quite like the effect though, it makes them look like they were applied by brushes or rags in the field;

The balkenkreuz are Peddinghaus stencils;

I added numbers to the rear of the turret bin as well. The white cross is the unit marking for s.pz.abt 506, used from the end of '44 onwards, to replace the lion & W symbol;

Finally, I added the decals to the fire extinguisher;

It still looks 'factory fresh' at the moment. I faded the markings with a very diluted base yellow. Everything will blend in better once the filters are on.
Hopefully i'll be able to show you all my experiment with permenantly muddy, but useable, tracks.

Cheers,
Rik
