I did some digging and found out how the turret was entered. I didn't know the answer to your question either, and I became curious too. It caught my attention because I am a former US Army tanker like your Dad was. I wanted to find out as well.
This is what I found out.
The original crew was 9 men. The vehicle was heavy, very underpowered with a 20 horsepower 4 cylinder engine, and it only had a top forward speed of 10-11 MPH. It could go 1.86 MPH in reverse. Wow, that's lightning fast right there ! 🙂
Even though it was slow and didn't do well off road because it was top heavy, (and also too heavy in general), it was very well liked by the men who operated them.
The turret was not capable of rotating a full 360 degrees like today's modern tanks do. Instead the traverse was limited to 260 degrees of rotation. Combat experience found out that one of the assistant MG gunners was not needed. So they reduced the total crew number down to 8 men from the original 9.
There were originally 5 men in the forward part of the armored car. They were the driver, commander, main MG gunner and two assistant gunners. The two assistant gunners not only loaded the MG's, but they could also operate the other MG as needed. Eventually the 5 crewmen here were reduced to 4, after combat experience revealed that one of the assistant gunners was not needed.
These forward compartment crew men were not able to reach the other 4 members of the crew that were located in the turret. They were sealed off by the armored plates.
The turret was manned by 4 other men. One man was the gunner, a loader, ammunition bearer and either of the last two could operate the MG in the turret as necessary. The fourth member was the driver, who was needed to operate the vehicle in reverse. They often retreated away from the enemy / target by simply having the rear driver take control of the vehicle and drive away in the opposite direction.
This was safer, because they didn't have to turn the car around in order to retreat when they had to. It was also faster to operate this way. In a matter of seconds they could be bugging out.
The turret had a butterfly hatch on the top. This is how the crew entered the turret. They usually didn't enter the turret once underway on a mission. Instead they climbed up on top of the turret and entered through the hatch before the mission began. They remained inside the turret during the mission, and exited only when they returned back from the mission, or in cases of emergencies like the vehicle became stuck, disabled, somehow damaged, or even caught fire.
Hope this helps answer your question. This is a fascinating armored truck. It was built on a truck chassis that originally was manufactured in the USA, then exported to other countries.
This is a screenshot from one of the websites I visited to find the answer to the question.

Take care buddy.
