Canadair Argonaut/ North Star freighters

[The AvgasDinosaur]

Dear All,

C/n 160 G-ALHN was apparently "modified" after BOAC service prior
to delivery to Overseas Aviation by Marshalls at Cambridge to a
freighter config. Photos prove this did not include a freight
door, she flew for some time with Overseas and Flying Enterprise mainly
on IT passenger flights and the occaisional freight run.
What was the nature of the modifications in early March 1960?

C/n 134 CF-TFJ was converted to freighter configuration during
service with Trans Canada Airlines what was the nature of the
conversion, did it include a freight door?

C/n 147 CF-TFU was converted to freighter configuration during
service with Trans Canada Airlines what was the nature of the
conversion, did it include a freight door? Photo evidence exists
of the starboard side showing the windows either blanked out or
painted over.
Did these two remain pressurised when flown as freighters?
It is possible that as many as 4 saw freighter service with Trans Canada
C/n126 TFB fleet 202
C/n134 TFJ fleet 210
C/n147 TFU fleet 221
C/n149 TFV fleet 222
Were any RCAF aircraft equipped as freighters??
Hope someone can help, Does anyone have port side rear photos of these aircraft, please
Thanks for your time and trouble.
Be lucky

Were any RCAF aircraft equipped as freighters??

The RCAF DC-4M s were basically unpressurised C-54s with Merlin engines so had the C-54 style freight door. See.....

Checked through Larry Milberry's excellent book NORTH STAR. Many photographs of RCAF North Stars with freight doors but no civil versions.
Air Caicos operated freighters but they were ex RCAF aircraft.

If its of any use, I took a few photos of BOAC Argonauts in the late 50's - go to www.abpic.co.uk enter Brian Doherty then select photographer.

The definitive -and excellent- book you need on the North Star and Argonaut is "Canadair North Star" by Larry Milbery published by Canav Books. It covers all the history and all operators of this aircraft which probably saved BOAC in the late 1940s and through to the delayed introduction of the Britannias from 1957. Unglamorous, noisy but reliable it gave excellent service mainly to Africa and all points east (but not beyond Singapore to Australia, the preserve of the Constellations).

I have both Larry Milberry's books "North Star" and "Canadair 50 years" which is where much of the info in my original post comes from. However they do not detail the conversions/modifications made.
Thanks everyone for your contributions so far.
