Aiming training device? I’d please

[Rrickoshae]

Good morning, Not sure if this is for this forum but thought someone might know what it is.
please see the attached photos of a device which would appear to be to enable trainees to be taught aiming techniques in a classroom setting. It is articulated, has crossed hairs and a flip up graduated piece. Any thoughts?
many thanks, Dave

Hi Dave,

Yeah I have one as well >>> it's the sight to align a heliograph.

Well done Drew, I would never have guessed that! It just goes to prove that there is always someone who knows! Thank you
Dave
