After reading all of this I have actually come up with a solution.
Maybe during the process the NOS pf may take scratches or other damage and returning it would be bad and just cause a problem between Mirco and the volunteer of pf.
The solution for helping Mirco make money doing this would be " You get a repro pf for sending in your NOS pf and because your original may not be in the same condition as you sent it in, Mirco gives you a second repro pf to cover the nos pf"
If you didn't want say another exact pf to cover the nos you sent in, then maybe a different pf from Mirco's catalog to cover things.
I would do this deal as it's beneficial for all parties involved. What do you think of this going forward?
