This is a nice little Motorola set that appears to be in relatively good shape. None of the external plastic case is broken although the power cord has been cut off.

The outside is very dirty but seems to be cleaning up nicely with some waterless hand cleaner on a paper towel, well, lots of paper towels and cotton swabs.

So far the only obvious broken parts are the two red plastic mounts for the front door hinges.

Here's a close up of the hinge inserted into the space where the hinge mount should be supporting the hinge. I'll have to do some thinking about out to manufacture something to do this. Since the on-off switch for the responds directly to the opening and closing of the front panel on the radio its important to find a fix.

The underside of the chassis has a nice date stamp of May 4, 1949 and when that panel is removed you get a look at the wiring and components housed there. A lot of stuff packed into a small space so replacing caps is going to be a little difficult.

Fortunately it looks like all the transformers are still intact (unlike the Philco 39-7 I just set aside),the tubes all test out OK and the loop antenna housed in the front panel ohms out OK.

Bob, Nice radio.  I’ve not seen one before.  Keep us updated!

This would be the second portable in the "other radios" forum where I have a similar one in my collection. I have a Canadian market Phillips portable that looks identical to the Motorola 5A9M Bob just posted. It's called a model CMB41L here is an example: https://www.radiomuseum.org/r/philips_cm..._41_l.html and even the chassis looks the same, not sure of the wiring. I will have to look it up but I think the Phillips may be a 1951 model, so maybe they bought the tooling from Motorola in Chicago, and started making them in Montreal? It's sort of odd because Phillips bought out Rogers after the war, and were making most of their sets in the Toronto area as that was where the Rogers-Majestic factory was. I believe that Motorola also set up a factory in Canada around the same time, though I will have to find out when, and where. They riveted a brass plate over where it says "Motorola" on Bob's set, and put a sticker over the plastic button that releases the lid. Here is the service info on the Pacific TV site: https://pacifictv.ca/schematics/philipscmb41ldata.pdf

Hello All;
I found the CMB41L down in the basement, it is definitely a 1950-51 model, the capacitors have date codes from February and April 1950, and the tubes have patent dates of 34-51 stamped on them. There are two toilet roll style filter caps mounted above the chassis in a metal band, and a date of April 1950, both made in Canada, I may restuff the cardboard tubes since there really isn't anywhere else for the replacements to go other then there, plus they can be seen with the back open anyhow. I also found a 150 ohm sand resistor, 2.5 Watt, just ahead of the selenium rectifier, in typical fashion the ends are turning green so it has to go, the main dropper for the filaments is a nice enameled power resistor, so it's probably fine. The chassis is pretty cramped so it's not surprising that not much work was done to it, they probably used the set until the filter caps crapped out and then put it in a closet after replacing it with a transistor radio.
The hinges for the front door are mounted on some plastic insulators, in a sort of shallow "U" shape, but the plastic appears to be different from the ones used on Bob's set, it's clear plastic, with a bit of a rubbery feel, possibly Tennite II as they have some mold on them. The plastic mounts had a pair of pins that plug into some leads above the chassis to connect the antenna, there does not appear to be a wire connecting the antenna loop to the pins so I think they rely on the hinge springs for that purpose. How you would recreate this would take some thought, maybe some ABS plastic, or nylon, they are about 1-1/4'' long, 1/4'' deep, and maybe 1/8'' thick, with a 3/4'' channel inbetween for the hinge.
