OC76 pinout?

I'm putting together a BYOC Tonebender.  it was shipped with OC76 trannies as opposed to the OC75s that are described in the directions. 
These are the trannies i have in the kit.   http://buildyourownclone.com/parts/semi-conductors/transistors/oc7690.html
any help would be appreciated.  I've googled the datasheets and have had a hard time finding anything.

Thanks!

There's no dot.   These are the metal can ones.

Some visual assistance.

If that's not it, then you can figure out any transistor pinout with the diode test on almost any digital multimeter.
You could start by assuming the middle lead is BASE, and you know it's PNP, so the BASE gets your BLACK lead.  Now touch the RED lead to another leg, write down what the meter says, move the RED lead to the other leg, write down the number again.
If the BASE was indeed in the middle, you'll get two number like 0.185 and 0.189.

The larger number (0.189) would be the emitter, and the smaller number is the collector.

For Ge, the readings should be within 0.100 to 0.300.   Numbers well outside of that mean you'll have to guess another leg as BASE.

The metal can ones normally have dots. I am surprised they did not mark them for you.

Basic multimeters should have the tester on them.
