Family history

My brother in law passed recently, I managed to find images I took of him shot quite some decades ago and got them digitised today, So in a way it's today's image. There's 21 shots of him, mostly with his dog Peoss, on the 1 roll. Heading off to visit family so a good moment to share.
I think the film is Tri-X
Likely shot on the Pentax MX with the Hoya 80-200
