Berliner Automatic Grand Sound Box

[Lucius1958]

Now, this has me puzzled: if the diaphragm is full sized, what do those screws on the front bezel attach to?

Bill

Much like the smaller Automatic that uses a three prong spring steel spider on the reverse to retain the inner part to the outer casing (sealing the whole sound box).

The AG uses three curved spring steel keys held by a screw. These keys fit into a groove that is in the main body and retains the front cover that also seals the whole sound box tight.

Hope all this makes sense.
