The Mouser 25LM022 is an excellent crystal microphone
cartridge.  It is significantly smaller in diameter
than the original Astatic cartridge.  However, if you
use some scrap pieces of styrofoam you can center it
in the D-104 housing without any problems.  The
original cartridge was held in by 4 narrow strips of
foam rubber but they are "way" to small to use with
the Mouser cartridge.

I do know that Mouser is back ordering the 25LM022
right now (I have had 2 on order for several weeks). 
Their stock is supposed to be replaced sometime this
week.  I guess that all of the "talking up" of the
cartridge on the various websites and reflectors has
caused their stock to become depleted.  At $3.52 each
they are also a good "buy" as well.

I had seen pictures of it and interpreted the image as
being roughly the size of a D-104 crystal element.
Hard to tell as it didn't seem to indicate any
measurements. Or I could be mistaking it for another
replacement element and confusing them.
