Simply stated (I am not a tiger expert) You have an early version Tiger I with the Feifel external air pre-filters (early Tigers were used in Africa). The filters were generally removed when back in Europe. The rubber tired road wheels were used on early and mid Tigers but the commanders cupola was changed on the mid and late versions. The late Tiger got a slightly different track (chevrons) a smaller track idler and steel rimmed road wheels. There are plenty of other things like headlight(s), tool storage, turret top changes and others.
So to answer your question, focus on an early tiger with or without Feifels and build it to suit you. I've no proof but I am sure some early Tigers made it to the end of the war so your paint job/camo is up to you. Depending what period of the war could give aid to what camo pattern used and how much wear and damage incurred (missing or bent fenders, battle damage, zimmerite or not and so forth.
