Restored 1920 Dorris K-4

I found it in a barn in Montana. After 4 years and
lots of work, my labor of love is 100% restored! The RV of my
dreams reaches a top speed of 15 miles per hour,
lacks front brakes, uses oil lamps for headlights and features a
dashboard intended to deflect debris rather than display information.
I included a picture below. Does anyone have
any idea of the value and do you know of any other fully restored
K-4's?

Thanks.
