Two pictures of 91556 , still in  camouflage scheme , as N322WN and operated by the Washington State DNR (Department of Natural Resources). Pilot here was Mr. Dave Longnecker. Both photos were taken late Spring 1974 and were published in "Kaman Rotor Tips"  issue of  Sep-Oct 1975 (page 17) .
The DNR used 5 HH-43F's for forest fire-fighting during the Summers of 1974 to 1980 - the "2" was used to aid in the communication with the fire-fighters on the ground.   

Comment from Mr. Jay Rideout - 2 April 2007 :  "In 1974 & 1975 N322WN was still in camo with the national insignias spray painted over. The pilot and co-pilot doors and the outboard vertical stablilzers were bright yellow with the red "call" number (Rotor 2) like the silver sister ships.
Ray Albee related a story about the ferry flight from Davis Monthan about a conversation he had with Dave Longnecker during the flight. Ray and Dave were commenting on how well N322WN disapeared into the background , really highlighting the need for some high visibility markings.
Ray Albee was the pilot that I worked with in '74-'75. We took great pride having the first helitack team (helicopter, chase truck, and crew) fully operational each of those two seasons. Appreciate the information... Thank you!!"
