And If you did, tell us the story about where when how and what you learned about the experience.

Picked up for 10 dollars at a surplus shop, with about 10 more.?ÿ I picked the cool one. Sometimes you just stumble across things that mean more to you than you realize at that moment.

Nope.?ÿ Not me.

I'm old, but not that old.
Thank you,

I've been in this profession pretty much all my life and never knew what one looked like. Dad talked about turning angles at night and I assume that was what they used.
Me. "What's the difference?"
T.C. Carroll "It's the difference between right and wrong!"
I came across a pile old round batteries at a triangulation station once that probably powered something like this.?ÿ This got me to recover my field notes from 8-20-98, where we recovered station Patterson along the west side of the Snoqualmie Valley.?ÿ The data sheet (sy3534) still exists and the monument probably does too as the property is still with the same owners and he was very interested in keeping it.?ÿ ?ÿ
Standard lamps used for night observations (triangulation and traverse).?ÿ From the pictures they look identical to the style I used with the Army in Europe (68-70).?ÿ Easily seen 30+ km away.
