I need to know what this is or waht it was used for. All I know is that it was made around 1949, its about 4-5ft tall, really heavy, and the brown part is wood while the top and bottom is metal.

It may be a weapo cuz it looks like a huge bullet. If you know exactly what this is, then let me know please. Thanks!

Update: could be part of texas history since my location as well as the object is in south texas. Anyone from Texas with knowledge of Texas history should check it out. BTW many thanks to those who already answered.
