Ah Hanno.

It's great to be able to sit back and watch a genius at work!

Thank you so mush!

David,

Here are the two features you were talking about:

1- Cipher clerk window to pass messages outside in the tent were the removeable table would be installed .

2- Starting coil isolation for the wireless truck.

It is so much better with pictures.

My friends,

1- Here we see the aerial chimneys and ceilling lights.

2- Here is an interior plan drawn up by our friend Bruce Parker a long time ago .

You are another genius at work here, Robert.

The passthrough still present in the Cypher Clerk's window screen suggests it is probably still the original copper screening. There would have been a spring loaded flap covering it on the outside to keep the weather out. A number of years ago, there was an apartment block here in Winnipeg built in the 1920's and each apartment door was equipped with exactly the same mail box slot assembly. It was torn down about 20 years ago, but very carefully salvaged of all the beautiful woodwork in it. I could not find out where the doors went because it would have been nice to know a source of supply for those mail flaps.

Yes, that is the coil isolation point under the hood. The two holes on the right (vehicle right) held an extension of the coil box that mounted a large filter cap. The coil box would also have it's own cover assembly.

Nice work Bruce did with his sketch. It jogged my memory once again regarding the 110-Volt Onan set up and now it is really starting to puzzle me as to what is so special about that particular configuration for the 2K1.

As I mentioned earlier, the Onan also had a 12-volt feed that I had thought was tapped into the circuitry to cross charge the wireless batteries located on the floor of the box in the front right corner. Not quite so.

I found the Wiring Diagram from inside the lid of the panel box I had duplicated and had a closer look at it to refresh my memory. The 12-volt feed from the Onan actually has it's own dedicated armoured cable line which runs from the bottom of the gen box, along the right side wall/floor line, passing under the 2 x 4 supports for the wireless battery trays and along the front wall/floor line under the wireless table. Once it passes the large grounding strap of the big copper bus bar assembly, it jogs up the wall and ends in a standard elongate electrical connection box. Bruce has it very nicely drawn in. On the floor at that point under the wireless table would have been a bracket holding two Grant Batteries. Those batteries are pretty specialized bits of equipment back in the day, which just adds to my curiosity about the whole Onan setup. What purpose was being met with all this specialized equipment?

Got some time before dinner, so I think I will try scanning in the shielding installation info I found earlier and see if it takes OK.

David,

Grant batteries , you got me there again.

What are they ?

In the pictures , taken inside Mr. André Gibeau 's ( whom i highly respect ) box

at the War Museum we see the bus bar you are refering to.

Still in Mr Gibeau's marvelous truck in the War Museum we see the 12 VDC feed of the + and - poles with external feed to the table just outside the box.

The cable that feeds the power looks like it's coming from the front wall and thence the right side wall where all the current is regulated through the panel .

Mystery solved ?

Gents,

- 1- Wartime picture in Canada of a C-15 A cab 13- round hatch Wireless 5 .

Snow on the ground , so winter of 44-45, H Huts , so a base in Canada , canadian civilian cars , so active base not a storage yard.

The best picture i have ever seen of the ''Gin Palace ''

-2- ( unrelated to the subject ) The Bomb from the Sherbrooke Fusilier Regt ( 27 th Armoured ) , the only Sherman to make it from D Day to VE Day.Also, from the unit that killed Wittman, the Nazi idol . Broadside , from a Firefly variant of the Sherman . Wittman tought he was rolling through wheat fields in Ukraine pushing back retreating reds. He met the Canadians in Normandy instead .

I think the scan of the Ignition Shielding Information worked out OK so here (hopefully) are the first five pages:
