Pinout for Orion P20005C LCD

Curious if anyone has run into one of these little guys. I've salvaged it from some scrap equipment. It's got the standard HD44780 - A00 controller. Looks like 4x16 chars. Tried google-ing the part number, but didn't get anything. I know it has a built in backlight, 16 pins, one end of the row is labeled "1" and the other end is labeled "K". I assume pins 15 & 16 are for the backlight, but not sure about the connections. Figure it's probably a standard pinout I hadn't run across yet.

hello, I am looking for P20005C lcd x 1pc (for repair).
You advertised that you have 1pc.
Can you sell this part? Thanks.
