Re: A high-priced Tektronix RM504


Yes - proving the authenticity of “NASA” property tags can be a challenge
given the wide availability of printers that can print on foil tags.
However, compared to tags printed using conventional printing techniques,
microscopic examination can show the pixilated edges of letters from
digital printers.

Also, a NASA property tag does not usually increase the value by much to
collectors unless that tag is on a flight item or a piece of equipment that
can be documented by NASA records or photographs showing the equipment in
use. You can find “owned by NASA” stuff all over eBay - from security
cameras to test equipment. Some value for non-flight hardware is high if it
was something specifically made for NASA and has the contract number on it
to prove it.

Then this RM504 is an exception to the rule.
By the way... how does one verify the authenticity of the "Blue and silver
sticker" on the front?
