This is 44-74908, former with RCAF as #9273 where it served with No. 402 Sqdn and suffered a belly-landing during 1956. Sold as surplus, it adopted civil registration N1070Z (5.59), rebuilt and re-registered to N965D (1963 / Charles Doyle), and finally N151BP (6.80 / Robert Pond).
I have a feeling that case #135 is 44-74908 N151BP in the colors it wore while owned by Chuck Doyle in the 1970's. I see Bob Pond's personalized reg# on the tail, so I guess this was shortly before it was repainted in military colors!
