USA Lite Made US Pat Dec 1921 Flashlight

Here I have a "USA Lite" brand flashlight. The flashlight is 6 1/4 inches long. The light end opening diameter is 2 1/4 inches. The cover over the bulb I am not 100% sure is the original to this flashlight. Also I could not find another similar to this light. If you happen to know what this light is called, or more information on it I am open to hear it. From my research I believe I have priced this flashlight fairly. The flashlight is still fully functioning and works. It requires 2 D batteries not included. It also has a small hook at the end that pulls out and flips up to hang this light up. The battery compartment is clean, and not corroded. The cover over the bulb does have a chip in it that can be seen in the pictures. This flashlight is a personal item I decided to list on my site, and has been with my family a long time. I also made a small YouTube video showing this working. You can find the video by searching "1921 USA Flashlight" on Youtube.
