If you want to get nitpicky, you can add the filled in periscope ports over the driver's visor. These early Tigers had them filled during production when the periscope was deleted from the design. The gunner's sight holes in the mantlet can also be moved closer to centerline.

Over at Tigers in Focus, the fellas have recenty discovered the turret numbers of several previously unidentified Tigers, including the 111 and 121. Previously the only turret numbers we had photographic evidence for were the 131 and 142.

Nice job!
