Barry I dont recognise the place where that CF Marathon was taken or even the CF reg. The second picture was at the side of the main working hangar. That looks like the Proctor fuselage in the background which may have been the one owned by RR, and the DC4.
That side of the hangar was a scrapping area and the last of the Spartan Mosquitos was there for a long time before being broken up. The Marathon had a spar life put on by HP and the Marathon in the picture was scrapped because of this.
