OC 44 pinout?

Hi, does anyone happen to have a pinout for an OC44 PNP Ge transistor?  I have googled far and wide and still have come up lacking.  Thanks.

  If the DMM has the HFe meter it won't test for leakage but will give a 'gain reading, anything in the ballpark on the PNP side of the socket means the pinout is now printed on the DMM.
  Some flipping around of the transistor may be needed, notice the sockets are 4 pins on each side [PNP/ NPN] to accomodate various transistor pinouts.
  Ballpark is usually 40Hfe through 300Hfe or so for GE's, but some vary even more.

they are common with most other PNP germanium transistors, ie the AC128.

Collector is the side with the red dot. Base is the middle, and of course emitter is the remainder.

How do I know? Just made a cool fuzz with them last night driving some OA7's.... OHH YEAH.. (:

OK, so doing a gain test on my DMM and possibly hooking up the transistor wrong won't kill it?  If so then I'll give that a go.

Also my OC 44 has no red dot.  Thanks anyway to all who replied.

If you orient it wrong, there is a chance of frying it.  As far as I know, doing an hfe test won't hurt, but it's a whole different story when sticking the thing in a circuit.  Check with your DMM.
