A January 1943 Tiger might not have S-mine launchers, though it would have the welded bases. It might not have the starter handle shaft stored on the bottom rear. It might not have exhaust shields. It might not have the standard turret bin; there were several prior types. It might have the small holes above the driver's visor, or they might be plugged up.
It would have 5 long portions of the gun-cleaning rod stored on the hull top. In February they were changed for 6 short ones.
In March, the rear engine cover plate was changed, causing the latch on the engine hatch to move. The Feifels were simplified. The turret got an extra periscope. Around this time, the tracks were added to the turret sides; 8 at first, then 7.
In April, the sprocket design was changed, and small legs were added to the engine hatch.
In May, the frames were deleted from the rear mudguards, and the engine was changed to a HL230. I guess that's where you stop.
All of the above Tigers had smoke launchers.
The insides of crew hatches were normally painted in the external base colour.
