Transistor Specs

[Christopher_List at Sonymusic.Com]

  Hi guys,

  I have these 2N5179 NPN transistors here - but I can't find data sheets
  for them any where on the WWW.
  They are 4-pin (?) metal cans.

  Anybody what the pin-out is for these (or even the standard pin-out for
  PNPs in this kind of package)?

  - Much thanks,
  CList
