C42 in M38
 

Hi,
I am going through a box that I acquired that contains from first glance, a complete C42 set. I have a number of questions.
The included manual is Operators Handbook, Radio Station C42, Truck Utility 1/4 ton CDN dated 1960. It appears that the set was in a M38. Questions:
are the resilient mounts (rubber blocks) shorter than the J1 box and the 4 Way No. 4?
The mounting NBW (nut, bolt, washer) for the J1 box and the 4 Way No. 4 are 1/2". The manual says 5/16"x11/4".
There are four "washers". They are like a mini coil. What are they for?
The set has a base and a carrier frame as in the manual. Page 8 indicates " position assembled radio set on runners engaging dowels at rear. Secure with two hand clamps at front." These runners and clamps are not present.
A large 27 1/2"x13 1/2" mounting plate did come with the set. It is stamped 5820-21-850-5914.
A spare tire mount for the ATU also came in the box. I am thinking that the set may have been in a M38 at one time, but for some reason changes were made which would account for the large mounting plate.
Photos attached.
Comments welcome.

Attachments didn't work first time.
Hopefully they will this time.

mystery washers
 

If I'm not mistaken those mystery washers will be located under the front securing clamps that you mentioned. They put some tension on the clamp to prevent it from working loose over time.

C42 info for m38
 

Hello Ian

There are some photos and information on the c42 in m38/m38a1 in:

Wanted: Canadian Manual for C42/C45 Installation in M38A1

The tray replaced the earlier mount which was bolted to the fender directly.

Thanks
Eric

Those large mounting trays are what I remember in the M38A1s back in the late 70s when I joined.
Those washers are, I believe, called a thackery washer. Seems to me there are some located on the top and bottom trays of the radio set on those brackets that lock the transmitter and power supply unit into place.



I have some of the original mounting brackets out in the shed waiting for a suitable project. I also have a couple of C42 sets waiting for the same.
