Canada's first Tracker, with MAD boom extended and radome lowered. Delivered to DHC as a pattern and test aircraft in May 1954, serialled X-500. Transferred to the RCN 13 Dec 1954 as 1500 (carried below the tailfin in this photo) and loaned back to DHC. Returned to the RCN 18 Dec 1955 as 1501. Converted to CS2F-1 standard, f/f as such 8 Jan 1957. Eventually to the Shearwater Aviation Museum for display. Often incorrectly quoted as ex BuNo 136519, but its identity is in fact unknown. Sources say that this aircraft was assembled by DHC from sections supplied by Grumman, in which case it may never have received a Grumman c/n. Tracker production numbers support this claim.
