Wayne Grant kindly sent me this photo of this enlarged Convair CV5800 (ex/C-131F, cn277):
It was ferried from Canada to New Zealand in Oct.2004 and is seen on a lease by Airfreight NZ from Kelowna Flightcraft. On 07Jun16 ZK-KFS was seen at Kelowna in B.C., Canada: obviously returned to KF.
Air Freight NZ ceased operations in 2016.

I have a March 2018 photo of this CV5800, as C-GKFS, shared on my Photos by Friends & Guests #55,
at Vancouver IAP ramp for KF Aerospace.

I came across C-GKFS at Victoria IAP and Vancouver IAP - see my CANADA 2019 report.
