Look at the Hetzer internals.If you look at a Panzer 3/Stug 3 hull theres a lower front plate to the nose, the semi-vertical nose plate, the sloped upper plate of the nose then the upper deck of the nose with access points for the transmission and gears, then the vertical front plate with the drivers visor. Thats at least five plates that need cutting, welding, fitting, hinges, fitting hatchways into access points, locks etc before you move back behind the drive sprocket..
Where was the Elefant? I didn't know any even survived the warI'm going to have to put that on the 'to do!' list.
Last year i ticked off the Elefant, that leaves the King Tiger and the Puma i need to find from the big cats.
All you have when buttoned up is the Gunner looking out that periscope with a small field of view, the TC had nothing except a rear facing periscope, and the driver that small frontal periscope.Just the complexity an expense of optics in the Stugs commanders cupola is incredible, the Hetzer lost that in favour of a simple scissor periscope.
