The short clip, which has been viewed 342,000 times on the video sharing website, is said to feature a woman named Gertrude Jones who is seen speaking on a pre-war prototype of a mobile phone developed by a communications factory in Leominster, Massachusetts, the Daily Express reported.
The video entitled 'Time Traveler in 1938 film,' had first been posted online a year ago and was widely reported on by various blogs, but it was only recently that a user who goes by the name 'planetcheck' came forward, claiming that the "woman is my great grandmother Gertrude Jones."
The user said that Jones was 17 years old and when the user asked her about the video, she said that she remembered it quite clearly, saying that Dupont had a telephone communications section in the factory.
'Planetcheck' asserted that Jones said that Dupont had been tinkering with wireless telephones and she and five other women were given these wireless phones to test out for a week.
The user added that in the video, she is talking to one of the scientists, who is holding another wireless phone, and is off to her right as she walks by.
If the claims are true then it means that the clip was shot more than 40 years before the first cell phone, a DynaTAC 8000x, was made available.
