Interesting goings on here in NW Oregon yesterday. First, several aircraft with registration numbers all leading back to "CE-172 Aircraft LLC", which appears to own quite a few Textron 172S aircraft. I saw N1658C and N1683C in the air, both of which have requested from the likes of FlightAware to keep their tracks private. A bit later, I saw a UK-registered helicopter, VP0CBW, in the air obviously doing a tour of the area. I managed to grab a picture of that aircraft as it made a loop of Newberg, OR, but I haven't been able to find a thing about it online. Picture attached. It's not a small helicopter, definitely not what we normally see for sightseeing tours. Also, earlier in the day, I caught two KC-135's overflying the area. Not sure if all of these are related, but certainly interesting.
Your helicopter is an EC225 (Super Puma), which is actually registered N255EV now, as of October. Presumably the Mode-S box has not yet been updated. Here is what my database says about it;
