An interesting (if somewhat arcane) find on eBay arrived a couple days ago.

It's a prototype or test version of the Azimuth/Elevation analog cross-pointer from the shuttle's aft deck (Panel A2; Remote Manipulator Arm) as can be seen in the upper left corner of this photo.

Upon opening up the case, it is clear that the device is more a close copy of a functional cross-pointer, intended only to look the part and probably test the lighting aspects of the design. Note the "Lighting Master" designation on the meter label along with the bolted-in-place pointers themselves. Only two wires emerge for energizing the LED lighting strip

Does anyone have further details on the NAS10-11500 contract number? The only thing I could find was related to non-destructive evaluation of shuttle tile bonds, which didn't seem correct, but maybe I'm looking in the wrong places.

The meter is a heavy fellow, and a small reminder of what is almost certainly an omnipresent design tension between launch vehicle weight and component robustness.

It's also interesting that such effort went into a test/evaluation example. Seems like it almost would have been cheaper to use a functional version than it would be to produce a one-off faithful mockup. Maybe further contract data would help clear that up along with this meter's role in shuttle avionics development.

Thanks in advance for any additional information.

Nice find. NASA likes lighting mockups. Most shuttle gauge specs list a lighting mockup as a required item. I have a Surface Position Indicator lighting mockup that has similar details.

In fact I got that mockup gauge and a few other items in 1990 as part of a plywood partial cockpit built specifically for lighting evaluations. It was my very first space hardware!
