Check, those yellow bombs, i can't remember if they were the colour for the RAF training ordanance or standard colour for pre/eary war live ammunition.
Bish: I think they are early war live bombs. I don't know when the color change came about, but by the end of the war, RAF bombs were a dark green.
The Hampden kit carries markings for John Hannah's plane when he won the VC on 15 September, 1940; maybe early enough for yellow bombs. At least that's what Airfix says!
Anyway, I researched RAF bombs previous to painting, but didn't come up with much.
Here's a photo of yellow bombs going out to a four-engine bomber. It's a Short Stirling, I think, which didn't enter squadron service till early 1941. Unless it's a photo of a training mission, yellow bombs were still in use.
I also found a photo of several types of bombs--some yellow, some green. Looks like the picture may have been taken in a museum.
From other information on the web, it seems that the British Army and Navy started using a buff color to identify ordinance back in the mid-1800's, and aircraft bombs kept to this through WWI and into early WWII. The color was changed to a bronze green to help camouflage them in outdoor bomb dumps.
I wanted to dress up the bombs, but couldn't find any green decal stock. I painted some ink jet white decal stock green then cut stripes.
The green stripe is said to indicate that the bomb used Amatol as an explosive.
A red stripe was added around the nose to indicate that the bomb was filled.
Tried the same thing with painted decal stock for the red band, but it defied my efforts and wouldn't cooperate. Even though I coated the painted decal with Micro's decal saver, they still just fell apart and shattered.
Based on the first photo above, though, it appears that yellow bombs didn't always carry any striping.
Unfortunate that no one seems to make a decal sheet for marking RAF bombs. I checked Hannant's, and the only things available were decals for USAAF bombs.
So much for what I could find on British bombs!
