I'm currently in the middle of building up a 42' T-17 metal body with a Bell 500 phone element which i just measured @ 1170 Ohms. had to open up the inside of the mic a smidge about .012 or so to get the element to fit and had to turn down the Bakelite cover some what so it just touches the element to hold it in place

I found that if you remove the outer ring from a telephone T-1 or T-100 type, the separate parts (grill & diaphragm) would fit inside a T-17 I was working without any machining. I used a large, thin o-ring to ensure all the parts were held in place when the T-17 cap was put back on. But apparently not all "T-17 style" mikes have the same internal dimensions. A Sonetroics M-15 that looked a lot like a T-17's body was too narrow inside by a little to accept the disassembled parts.
