"J" Hi,
How accurate do you want your Tiger 1 to be?
I ask because you describe it as an early model,
If you mean one of the first 50 Tunisian Tigers then you have some good bits and some not so good bits! There is some question about the front step and grab handle, some people say it was fitted by the factory others say it was fitted by a British REME workshop to allow King George vi and other officials easier access to "131".
The first fifty had the Headlights mounted halfway down the front next to the Radio operator and the Driver,
The Turret Mantlet was mainly flat and if you intend filing and grinding yours to that shape you should be aware that the metal on the TORRO/TAIGEN Turret Mantlet is very thin and will need some filler.
The early Tigers had two vision holes drilled into the area above the Drivers vision slit, most of them were filled in later and after the initial batch the holes were no longer to be found.
The front Fender was a flat sheet of rectangular Steel without the later hinged section, the same is found on the rear fenders as your other picture shows complete with the curve along the base and side,
That picture rightly displays the early pattern Air Cleaners and the correct exhaust shrouds.
The Tow ropes on the top of the body were mounted back to front when compared to all the later model Tigers,
With the exception of the Exhaust Shrouds everything else can be fixed with a little work with regular modelling tools.
The shrouds I made using the photo - etch brass from a "Voyager" rear fender set and the very few photographs available as reference.
And finally the first 50 did not have spare track holders on the turret, indeed not many had a track holder across the front

Good Luck!!! shaun
