Hi Alan:
The tracks are the kit one´s. As they come they´re wrong, I think they are the late type. To make them look like they are now It took me a lot of work
First I build them as they came. Then I sanded them to erase the raised detail and filled the space between the tracks with putty to simulate mud.
I´m happy with the result because I saw some pics of Tigers in a soft muddy terrain and they look similar to what I obtained with these tracks.
I didn´t want to invest in a pair of AM tracks in this kit, here in my countrie they are very, very expensive.
