Bob Dylan 12 Metal Acetate Master Recordings 5 Track Blonde On Blonde?

Excellent condition Metal acetate contains 5 tracks. No label,one sided disc. In crayon and on sleeve are numbers XLP 113763 dash? 2. Also on sleeve is reference Bob Johnson order 63791. Former owner had a small piece of paper with 6 titles written with 2 crossed out. Hard for me to read his writing so I took a pic and added to site. I have not played to check as I no longer have a stereo system. Maybe a Dylan collector can look at titles and date this. Judging by zip code on envelope it is newer than 1964. When I googled the XLP numbers Blonde On Blonde comes up.
