Prop: Repair/Repaint or consider it a learning experience and move on?

Hello all. Very new poster, Not very much experience (none?) in props and the acquisition of them.

I will try and keep this general in nature:

I have a prop that somewhere in time got broken, a large piece is missing. Repairs were made to blend in the area where the missing part used to attach. Then the whole thing was repainted beautifully. The difference being one accent color quite different to the screen seen items.

What is the consensus or opinions of those that are knowledgeable in original props:

1) Acquire the missing part and have it re-installed (if even possible to hunt down), with just paint work on the repair?

2) Same as 2 but repaint the entire item back to correct? (or maybe just the few areas that have the wrong color)

3) Enjoy it as is, while kicking yourself in the behind for not learning more before pulling the trigger?

I would say it depends on what it is and what's missing, but unless its the holy grail of movie props I would do what makes you happy. If it was already fully repainted by a previous owner (and not for use in another movie or something) in my mind all worries of keeping it original are gone. I'd go with #1 first... then... if and when you have the missing piece, debate on the touch up vs. more accurate repaint.

Thank you for the reply.
The provenance with the prop (which is not in my hand at this moment) supposedly traces the history of it. It was broken during filming. Production repaired and repainted it. At the end of shooting it was presented to the actor that used it. Its been in his possession up until being sold to a broker, then to me.

If it was repaired by the production itself, and you have documentation as such, i wouldnt worry about it. Shouldnt change the value too much, imo.

Defintely a different scenario if re-done by the production as opposed to another collector, but still I would ultimately do what makes you happy.

I went with option #4
