Sara you have a great family legacy. My uncle once had a really nice LaFever gun that he loved. He built a new house with a built in hidden gun closet and two weeks after moved in someone came and stole all his guns and his Lafever. Came in thru a back wall and someone with builder tipped of the thief(s) at a minimum.
I was just a kid when he bought it and it was the first true nice damascus gun I had
ever seen. This way back in the 70's and that is when everyone was afraid to shoot damascus guns and I don't think there were a whole lot of low pressure shells or loads being offered, if at all. Still remember my dad, uncles, grandad and myself ogling that gun and listening to family debate about bird dogs and shooting damascus guns and fear of blowing up. All I know is that was about the same time my dad had the bug for an old sxs and he really got the Parker bug.
That is an extremely rare human being. I think that dude is definitely over 7 feet and maybe closer to 7.5 feet. I found a list of tallest humans recorded in modern history and some over 8 feet tall. He could be that tall even but there is not scale. I did see a guy listed that was famous that lived from 1916 to 1959. His name was Lock Martin and he was reportedly 7'7". He was born in Pennsylvania but went to Hollywood and did some acting. He was the robot Gort in the movie "The Day The Earth Stood Still" That may be him.

BTW did not see others post of same website showing some one else. Its possible it could be that Tomain guy as well. Hard to say. Did see a picture of Lock Martins hands and then looked at your picture. Lock had some massive hands as well that would swallow a shotgun like in your picture. Good stuff hope you find out who it is.
