There is another thread with some quite detailed information about Edison Bell portables on the forum, but that machine has a double spring motor, while my machine has a single spring motor: viewtopic.php?f=11&t=49754&hilit=edison+bell+portable
As we can see one of the previous owner also had other interests than music, when looking at the lid cover

I found a small ball bearing inside the horn, and it must belong in the tone arm, since the tonearm is somewhat loosely fastened to the base. There is a small screw that opens the tonearm/base assembly, I know what awaits me there...a number of small metal balls. Still, I would like to try to get the small ball bearing back in position, if possible.
I picked it up for € 10 last evening in Oslo. I was visiting Oslo to see a gramophone friend, and saving this machine was an easy decision, even if my house and rented storage lockers..are full already. It is the first Edison Bell portable I have seen here, and the soundbox alone was worth the buy for me, really.
I am adding many photos, for reference. If someone need/want better close up photos of the motor, just tell me, and I will upload more after disassembling the motor. It actually runs, and as we can see it is a front wind motor.
The model number seems to be EB 321, looking at the decal at the bottom of the lid. At first I thought the lid stay was missing, but after looking more closely and checking the lid, we can actually see there are not supposed to be an internal lid stay, the external hinges at the bottom of the lid also works as springs and are holding the lid when it is all open.
We can also see wood carved out at the rim surrounding the horn, it is necessary to allow the turntable to spin freely!
