T-3 Headlights - Whats correct ???

[ORIGLS6]

All,
Here's what I found on the T-3 in my '69 Nova. Inside the triangle, the vertical lines. A pebble grain inside the letters T-3 and the Large T. At the top, embossed to the outside, J75. Top left, below the aiming tab, stacked vertically, 8205. Top right, same location, just the number 2. Both those locations are embossed on the inside of the glass. On the back of the light is a stamping in red-orange. The top line reads CO2. The middle line is a little smeared but appears to be D 8 26. And the bottom line is simply 12V. I'm almost certain this light is OE to this Jan 4, Ypsilanti car. For what it's worth!
