Hello,
Thank you very much for corrections. As I can see there is a controversy what happened with one R-4B ordered by the British in the batch of 45 helicopters bought for the RAF in March 1944. Sometimes various authors write that one of those R-4s was handed over to the RCAF. But there are also controversies as to the serial number of this helicopter. It came from the batch serialled 43-46500 – 43-46599, if I am not mistaken. Today in Canada there is one specimen serialled 43-46565 but its history is unknown. Does your book contain an info what was RAF or RCAF serial for this Canadian R-4B? The British serialled R-4Bs as KK and three digits or KL and three digits.
Best regards
C.
PS. And maybe exists a photo of this sole Canadian R-4B?
