Some very interesting shots there Clint
The date 1 May 1919 indicates it was the first conversion made and since no US Navy BuNo is
visible also indicate they were painted on the aircraft post conversion.
The four blade prop is interesting as well. Not seen that before.
Venturing a guess I would say that one was A5620
The photo dated 27 June 1919 looks like A5626 to me. What do you think?
The aircraft equipped with flotation gear was A5629.
But what is the aircraft which is
not a Hanriot (photo date 13 Sep 1923)? Have I seen that before??
Cheers
