The speaker is made of bakelite, I can't check if it works. It is in good condition, no damage is visible on the case.
On one contact (+) part of the screw is broken off, the rest of the screw is stuck in the speaker. Look photo. Very rare thing.
So:
Shipment within 1-2 days after purchase.
Tracker number to monitor the parcel.
No refunds.
I do not know working speaker or not, you buy as is, without possible claims. In the speaker on one contact broke off part of the screw, you can see in the photo.
You buy what you see in the photo. If something is not clear, ask.
