not good news
I have done some checking looks like no manuals to work with and possibly incomplete records 206B-1 not type cert compatible with other 206's. The avionics would need expensive certification, some of the part numbers don't even exist in the civilian Bell world. The engine is straight C20, really only looking at Warbird status but with Index 3 so no flight over population or adventure flights. With the interest that's seems to be there at the moment probably looking at 200-300k buy price and need to spend 200k to get it going so doesn't make much sense when there are so many Jetrangers in normal cat available, esp at the age these are at.
