Data sheet for FREQUENCY DEVICES 780RT-3 Band-Pass Filters?

[rockout]

I have 7 boards each with two 780RT-3's.
If you have the data sheet as a PDF file or can scan and send me the pages
that would be fantastic. Thanks for any help.
   
BTW, what do you call this type of device and does the
all aluminum case indicate it was used in aircraft?
