The seller is in Italy, there is no vinegar smell or warping, there is no fading (it is an IB TECH so I wouldn't expect there to be) it has the mono Italian soundtrack.
It looks to be in good condition for its age. As is usual the beginning and end of each reel is a bit scratched up, but the samples I have seen look like a print in good condition. The colour is certainly gorgeous and would be perfect as a reference to check against/regrade the BD release.
Going on the edge codes it is a 1971 print, so I think it is the original theatrical release, I'm not an expert on this movie, so perhaps someone else will know.
There are a few splices, but not too many.
The postage will be around another USD$200-$250 or so.
I can scan 35mm IB Prints @ 4K.
If there is someone in Italy on the forums that could help with the transactions, that would be great.
Drop me a PM.
