Sorry for the delay but here it is. I received this image yesterday evening but wanted to confirm it was authorized to share since it did not appear in the original collectSPACE article. I also wanted confirmation from another source what type of restoration, if any, had been done to Armstrong's Speedmaster.
Here the additional unreleased image of the Armstrong Speedmaster from the NASM (Smithsonian 2019) via collectSPACE. Thank you to cS for allowing me to share it here first.
The watch is all original and has only had a restorative cleaning. It was disassemble and cleaned and all parts are original to the watch as it was received from Armstrong by the NASM in 1973.

Here is an enlarged image of the watch where you can see the Serial Number #46 engraved on the lower left lug.

One interesting observation I made is the evidence of the restoration by the orientation of the scratches on the unpolished crystal. The large scratch you see from the center of the dial to the 5 hour marker is oriented differently from how the crystal was set in the watch at the time of delivery in 1973. If you look at the original images of the
Armstrong watch here taken in 1973 you can see the same large scratch running from the center to the 3 hour marker.
I hope you enjoy the new image of this fantastic piece of history.
