Help ID Infrared receiver

[Squidster]

I have 2 IR receivers which I can't seem to ID.
Both of them are 3-pins, with a tight-fitting metal bracket around them
providing another 2 legs for physical strength.

One of them says "S28", and the other one says "SD28".
The 'S' are pretty stylized, not unlike the 'S' from Superman.

Any clues as to which supplier are these from?
I'm trying to locate their datasheet...

TIA.

Shindengen, Sanyo or Sharp, probably the latter as I know they make IR receivers
