Bleg on Eleanor and Theodore Roosevelt carry handguns

Here’s a picture of Eleanor in 1934 practicing with the revolver she had obtained the previous year. What type is it?

Note: the Secret Service gave her the gun in 1933, when she insisted on traveling on her own without the agents. So the gun would be whatever the Secret Service was carrying in 1933.

The NRA National Firearms Museum collection includes Theodore Roosevelt’s 1900 Fabrique Nationale semi-automatic. The museum reports the Roosevelt family tradition that this was the gun he kept on his bedside table while he was President. It seems likely that this would have been the same handgun that he carried for protection while he was President. Does anyone have information indicating he carried a different gun?
