AUS CMP tyre loading ramp

[BSM]

Mainly a question for knowledgeable Aust. CMP owners/MLU members however any assistance would be appreciated. The first attached image displays the spare wheel loading technique and apparatus used on a range of CMPs by 2nd AIF troops during WW2. After the tyre was in place the ramp was stowed under it with the raised section at the end assisting in keeping the tyre in place. The ramp in this instance is a single piece of equipment and the vehicle width at this point was sufficient to accept the ramp length when stowed.

The Australian No.6. Artillery Tractor was designed to tow the Bofors 40mm AA gun after the supply of British Bedford tractors dried up early in the War. It is basically a C60S cab chassis with a locally designed crew cab and stowage binning. All No.6. tractors were fitted with winches.

At the front of the crew cab there is a compartment for a lorry wheel on the left and another for the spare Bofors wheel on the right, drivers side. There is no accommodation for any type of ramp. Documentation on this aspect is yet to surface however I am of the opinion that some form of ramp existed and the most likely stowage spot is between the crew cab and the brake man's seat on the rear deck as shown in image 2. The third image is believed to be one of the securing brackets for such a device.

Problem here is that the available width is insufficient to accept a ramp of the type shown in the first image, basically too short. The contention therefore is that if there was a ramp stowed in said position then it would have been made in 2 sections, either hinged or joined somehow. Can anyone shed some light on this topic.
Thanks in advance....Rod
