It is a Brownie Hawkeye camera flash model
Kodak made a slew of cameras bearing the moniker 'Brownie' from roughly 1900 untill the mid 1980s, ranging from box cameras to folders and frequently only having the name in common. The Brownie Hawkeye was available first as simply the Brownie Hawkeye camera and then flash capability was added to make it the Brownie Hawkeye Flash camera. Non-PC as usual for Kodak; this required a special Brownie flash called - wait for it - "Kodalite Flasholder Lumaclar Reflector". Yikes. The original has a metal wind knob, the Flash model a plastic wind knob and the word 'Flash' on the frontispiece*. The non-flash model was only made for a couple of years and so is slightly more collectible.
Maybe worth $10.00 instead of $5.00 =) I payed $1.00
