This added so much to my Tiger 1 Mid production from Tamiya. The sheet lined up almost perfectly with the Tamiya kit. Almost, except for two holes that had to be drilled out in order to install the large shovel on the front of the tank. The rest however matched up perfectly. This add-on was easy to install and the directions were extremely clear. I recommend carefully reading the tank assembly instructions along with the zimmerit instructions in order to ensure you put the zimmerit on at the proper time during assembly because it will be covered by other parts later in the build.
