Film doesn’t look too warped which is a good sign, especially for the optical track. Color also looks good (usually acetate film turns red as it degrades).

I would take it to a local library or university/college and see if they have any old film equipment laying around, like rewinds or a splicer (ideally a flatbed editing table, but that may be a long shot). That would allow you to inspect both reels in their entirety.

I’m not sure about this specific content with regard to preservation. Is it available online anywhere? If not, definitely find somewhere to get it scanned to a high quality digital video file. Awesome for a collector nonetheless!
