With RR Merlins RCAF, BOAC and CPA used three bladed props on their Canadair Fours

TCA used four bladed on the trans Canada fleet and three blades on the trans ocean although sometime four bladers were used sometimes

I read that the three blades were faster…..so perhaps that means the fours were more economical and maybe without the same competition on the Candian routes were a better bet where a little longer time was not an issue.

Tudors and Lincolns always seem to have used the fourblade.

I think the Science Museum one is a very early machine.

You could never directly compare them as one was a flying boat and the other a land plane

The only thing they really have in common is neither should have been built

Could you not have the original registration painted as normal with the real later issue small on the frame somewhere in the same way as war birds in military colours..

The colour pic on the Cambrian site could be misleading

It may not be a colour pic as a lot of monochrome were hand painted in those days

There were special paints made and my Mother had a set and used to paint folks wedding photos to make some cash

Also colour reproduction was not good then so postcards were not the right colours.

I wonder though if you wrote to that webmaster if he could actually give you the info you need…..one of the ex Cambrian guys may well specialise in their liveries.

If you mean the one at Gatwick……..last reports was it was still with the Fire Service there for possible none destructive training.

No reports are recent though
