Need Candlestick receiver ID

[wds]

I purchased a very old American Electric Wood Telephone, and it came with this receiver.  The shell is unmarked, but looks kind of like a Kellogg.  The cord is marked Kellogg.  My question is about the magnet - is this a WE magnet, or a Am. E. ?  The magnet is marked with a "Z".  Also notice those cheese head screws.

Never mind - it's a Kellogg Magnet
