Youz guys are so smart, here's a hard one, and I don't have the answers

Calvin Coolidge on Sapelo Island, Georgia in 1925 with his host Howard Coffin. Looks to be a deer in the wagon, and a dour Calvin has a long barrel double



Sapelo Island c. 1927 with Colonel Latrobe with a short barrel double





AP Sept. 6, 1928 file photo him shooting trap with a Model 12 at his vacation home on the Brule at Superior, Wis. He scored 29X37.



What are the doubles, and where are the guns now?
