Bish,
You're welcome. I've corrected my PS for the bombs as examination of the photo seems to indicate they are British 500 pounders because of the type of lug attachment.
Although American 500 lb AN-M64 bombs did have a single lug attachment point (seems like it was an Army / Navy thing), I do recall reading that the British did use the American 500lb bombs utilizing the single lug attachment. If I run across confirmation of that, I'll let you know.
Another PS> I do wonder if they're light green because of re-painting the old "yellow" bombs for camo purposes?
UPDATE: After perusing the 1946 Ordnance manual, I did find that American AN-M64s could be used by the British. They would use the one-lug connection instead of the two-lug connection used by the Americans. Later in the war, the British added a two lug connection also so the Americans could use British bombs in their aircraft.
Also, after staring at the photo of the Mossie being loaded, it appears that the nose rings may not be yellow, but might actually be red. The photo certainly seems to be color shifted towards the "green", so that may account for the discrepancy.
