I work in a school and see dozens of cameras in the darkroom so I can't do a

Thanks to all.

Sounds to me like shutter bounce in a camera with a vertically
traveling shutter such as an FE, FM2, F3 and many others.
Manufacturers such as Nikon switched to vertical travel in an effort
to increase the flash sync speed, top shutter speed and for other
reasons I'm sure.
