This M108 shows the large size of the vehicle that was built for a relatively small howitzer. The transmission access plates on the hull front top are visible, with their hinges just inboard of the lifting eyes. The howitzer travel lock is folded down. The doors on the hull's left side above the track were for access to the batteries. The driver's shuttered periscopes are visible on the left side of the hull, with the engine across from him on the right side of the vehicle. The cab left side door is open, allowing us a glimpse into the turret, and the commander's cupola can be seen on the far side of the turret roof.
The hull and cab rear doors as well as the cab right side door are also open on this vehicle. Unlike its twin 155mm SPH M109, the 105mm M108 did not require rear spades for stability when firing.
This view is looking into the open cab right side door, towards the left-hand turret interior. The large spring was part of the howitzer equilibrator mechanism, and the mount for the panoramic telescope M17 is beyond the spring.
This picture was taken through the open cab rear doors. The breech of the 105mm howitzer is on the far end, and the commander's seat back is visible directly in front of the open doors. The horizontal handwheel below the panoramic telescope mount is for traverse, and the top portion of the auxiliary elevating handwheel can be seen at the bottom of the image. The bar going across the top of the opening above the commander's seat was part of the fuze rack.
Looking through the hull rear doors, the traversing and auxiliary elevating handwheels are again visible, providing a reference to the above image. The turret traverse lock mechanism is directly below the light coming in through the open cab left side door, and the opening to the driver's compartment can be seen towards the front left corner of the fighting compartment. Parts of the left side hull ammunition rack can be glimpsed towards the rear of the vehicle, and just beyond this is the folded-down, woven seat for one of the cannoneers.
The opposite side of the fighting compartment is illustrated here. The elevating handwheel is visible at the front of the fighting compartment, and the engine air cleaners are the two locker-like structures directly below it. Parts of the right side hull ammunition rack can again be seen, but another seat for the other cannoneer appears to be missing.
