HP-65: Was this item in space?

[walter b]

Hmmmh - I doubt it for several reasons.

1. This seller is trying to sell this for a very long time.
2. AFAICS he's not showing anything which proves that this particular calculator was on a space mission.
3. Anything like a NASA inventory plate on the case would be nice but I can't see it.
4. I can't see what that postcard shall tell in this context beyond being a rare souvenir for sure. Same for the photographs.
   

Ceterum censeo ut caveat emptor.
