I don't think that is in any way a 'simple' antenna mount.

It looks to be a modification of the original "Aerial Base No.1" mounting (used with the Wireless Set No.11) where there was a tension spring to hold the insulator itself in the "cup" of the mounting. This was then modified later by adding the square adapter and flat plate on top to take Aerial Base No.8 (and later No.10) when the Wireless Set No.19 replaced the earlier set. The 7-hole (for the six mounting bolts and central feed cable) mounting that was introduced with Aerial Base No.8 has remained the standard to the present day, nearly 80 years after introduction.)

I agree Chris. It’s very complicated. It was originally done for the 11set. In one of the original photos there is what appears to be an 11set mounted in the truck. Or at least the charging board for the 11set. The Mk1* Carrier and Otter were also made to be able to fit the 11set or 19set.

Installed the tail, brake and convoy lights the other day. The pictures don’t do justice for just how bright these LED’s are. Even from a 45deg view they stand out. I’ll be going with two brake and two tail lights. I realize the original only had one brake but to be safer I’ll go with two.

Hi Jordan

I wholeheartedly agree that good visible brake lights are a necessary safety measure.

While the wiring diagram, in the manual, shows only one "STOP LAMP" two of my trucks 1945 HUP and 1942 Pattern 13 C60S appear to have been wired originally with two brake or stop lamps one each side.

So that rear of the HUP had two of the two light tail light brackets the drives side one has a toggle switch which turns off both tail lights (rear marker) turns on the black out or SUB LAMP which shines on the rear differential. The C60S has the sub lamp on the side of the frame in the form of push switch like the high low headlight switch
The brake light isolation switch is up on the dash.

When doing my first CMP wiring harness it was for my HUP which fortunately was very complete to copy, using the wiring diagram for the size and wire markings.

Cheers Phil

I also use the LED bulbs but went a little further with magnetic tow truck tail lights, with turn signals. I can fold them up out of sight when on display. And they add lots of visual cues to anybody following.

[Jordan Baker]

All good ideas. The harness came with separate signal wires installed. So if I add extra lights the wires are already in place.

Today was a full day spent in the shop. I made up the tray and cover for the Chorehorse generator. It was mounted on the left cab step. The Chorehorse is also mounted on a sliding plate so it can be dismounted. However it is my belief that it was intended to be run while on the cab step.

Yesterday and part of today was a sewing day. I made up the canvas that fits between the radiator and the cowl. This was my first time using a treadle sewing machine. I don’t really have the foot rhythm down but I managed to get everything sewn. I also had to make up some stiffened burlap to go between the layers of canvas. I used carpenters glue and water. It seemed to work very well to match the originals.
