It is going to be a Yarrows Helicopter Yarksis HASR.3A of the Royal BC Navy.
Teensy bit of backstory: Yarrows Shipbuilding of Victoria, BC, established its Helicopter Division in 1959, to licence-build the Bristol Sycamore (as the Yarrows Yoho); the Yoho entered service with the BC Army, the RBCAF and the RBCN from 1961, gradually replacing the Bristol-built Sycamores. In that same year the RBCAF received Belvederes from Bristol, and subsequently Yarrows obtained a licence to build the Belvedere in BC, too (as the Yarksis). Both the Yoho and the Yarksis were developed in multiple variants for all three (four, if you count the RBCM as separate from the Navy) branches of the BC Defence Force.
The only variant of the Yarksis used by the RBCN was the HASR.x. Like the HSR variant for the Air Force, the HASR was shortened from the base design (the Yarksis HC as used by the Air Force, which was identical in length to the Belvedere), although the naval variant was somewhat longer than the air force version - whereas the latter was exclusively for SAR duties, the naval version added an ASW capability.
The HASR.3 were the third iteration of the naval variant, which entered service in 1977, and from 1995 through 1999, all were gradually upgraded and life-extended by De Havilland BC (which had in the interim absorbed Yarrows' Helicopter Division) under the 'YUP' programme (Yarksis Upgrade Programme); the YUPped Yarkses were designated HASR.3A. This should keep the helicopters in useful service until about 2020-2025.
I've got a Belcher Bits CH-124A conversion kit that I intend to apply to this to reflect some of the YUP upgrades, and I'm gonna ransack the spare parts boxes to see what else I might be able to use for this project.
