That would be really cool if they can locate the rest of the film too.
Sadly some old time film collectors knew they had "lost" films and would not share the info with anyone. A friend of mine from Texas wasn't interested in films like his father was. My friend told me growing up his father would show him a film and tell him "...they think this one is lost, but here it is..." When his father passed away, my friend and his sister didn't want the collection, and couldn't find a buyer for the lot...way too many films...with a heavy price tag. Now the L.O.C. has them all...and they don't even know what they have.
I just wish at the time my friend had known I collected film...he said I could have had all I could carry.
