PCB says the model 352B65 is now a 352C65
(improved shock resistance) $400USD in 1998
http://www.pcb.com/products/svs/svs352c65.html
352C65 5-44 side connector
352C66 5-44 top connector
352C67 attached cable
352C68 10-32 top connector (larger, but cables are more common)

The photo looks like they used an adhesive mounting base
that I don't see on the website. Maybe a 080A15.

The blue goo looks like Petro Wax, also not on the web site
but is $15USD.

For a cheap DIY low frequency accelerometer, an Analog
Devices MEMS accel might be worth a try.

I'd try a
ADXL202 2g 2-axis (hey, it's stereo) digital duty cycle
outputs or analog output that would need a buffer
 or a
ADXL105 5g 1-axis analog output, no buffer amp needed.
Free samples. Tiny little surface mount parts that I have
a tough time soldering to.

That was some interesting stuff about phono cartridge
tree listenin'.
