This one had me double take, triple take and then just fell apart laughing.
First, I had to reconcile myself to the fact that you did not want an EXACT copy. This is unusual rpf behavior.
Second, I realized your interest in the display as a whole was more intense than in the replica, thus having obsessive tendencies but focused on a different attribute of the hobby/lifestyle. This would be perfectly normal rpf behavior.
Third, I thought "Ya, no one packs around calipers anyway.... except when I am out searching for match possibilities at thrift... or when...". And if I have calipers then my friends and visitors might also have calipers. So maybe the expectation that no one would be carrying calipers might not be rpf behavior.
Fourth and final and I am completely on board with this. You didn't say you didn't expect anyone might carry random measuring tools (calipers, swatches, a magnet, etc.). You said they wouldn't whip them out and measure something on or in the display (inferred). And here I can agree wholeheartedly due to the expected immediate aggression from the collection owner over my complete disrepect in touching a prized replica without permission.
AKA, I agree.
