[Boatanchors] classic microphone design

[Dick KF4NS]

I have an old Turner 454X SSB crystal mic the had a bad element and 
purchased one of Mouser's ceramic elements which by the way fits great, has 
great sensitivity and response.

Only problem is that the depth of the new cartridge is greater than the old 
crystal one so I must remove some the content of the element cover to get 
the screws back into it. The element cover has the outer screen, a cloth 
piece, another metal screen, a fiber washer, another screen made of brown 
fiber material with larger holes than the other screens, and finally another 
fiber washer.

Is this just alot of overkill or are all these parts in the element cover 
essential to the performance of the mic?
