Craigslist
I have for sale a Kuston Electronics KR-10 SP radar unit that was used by the Michigan State police in the 80's or early 90's. I bought this with the intention of restoring a 1980's Mustang pursuit car, but other projects got in the way.
The radar unit works. There are no tunning forks or remote with the unit. I will ship this item via UPS at the buyers expense.
Not my ad but might be helpful to those looking for this exact radar.
