That is a fantastic photo of the Venturas and Mitchells together Paul. I would assume the squadron is No. 1 (Bomber Reconnaissance) Squadron RNZAF flying No. 10 Servicing Unit Venturas from Guadalcanal from October 1943 as they flew several missions in formation with Mitchells as their lead squadron when they arrived there before they were fully broken in as a combat weary squadron and flew missions by themselves in their own right. I may be wrong though, if you had a date I could narrow it down more.
James, now you’ve made me scratch my head. I think the issue of Flightpath I referred to was Volume 19 No. 4 with the three shark mouth’s on the front. there’s photo of a Mosquito in there supposedly marked U-NA and somehow I had worked out and equated that this was A52-506 as shown below but now I can’t recall how I came to that conclusion. It was a few months ago mate. And I could be wrong. the photo is in the middle of pages 26 and 27.
