The IPB nude repros weren't cheap even back when Gene ran them. Years ago I got one second-hand, and Ron worked his magic on it. This was all before I even sourced a Creech for it. I was looking for a player's and ended up with a partially restored one which already had a pf that was touched up and cleared by Bill Davis. So, the new IPB nude is still not installed. I don't see the point in doing so until I have nothing better to do, so like, in ten years after I retire. Nevertheless, every pf that Ron has done for me over the years has been a work of art.
To the OP's original question - I would value the Kruzman restored original higher than a repro. Many would value it higher than a repro that Ron subsequently fixed the clear on. I would tend to agree. You just have to find the right buyer.
