Clue as to Hapets whereabouts. Investigators required

From Trip

There has been some discussion about the individual photo of Hapet and the year it was taken.
This is a screenshot of Hapet Izmirian in a group photo next to another photo of Hapet Izmirian in a posed photo. Don’t read any more until you have examined both photos. In which photo is Hapet the youngest? What is the age difference between them? At this stage I don’t know the answer. So your opinion is as strong as any.

Got your opinions. According to a book Jean Abrahamian has, the group photo was taken in 1920. Add or take your age difference off 1920 and we have the year Hapet had the individual photo taken. The individual photo was definitely not taken at Musa Dagh. The family members who have been discussing this with me agree the Uniform is too good to have been from the Musa Dagh region. The gun is also very modern for that era.

I am trying to gather facts to determine if Hapet was on the mountain in 1915 and taken to Port Said with the 4000+ Armenians or whether he was elsewhere.
