Short Sunderland upper wing roundels: which type & what size on ASW aircraft?

[Richard502]

Built the Sunderland in 1/700 that comes with Aoshima's Cornwall kit - w/o instructions, unfortunately. The accompanying decal sheet has red-white-blue roundels of about 2mm diameter. At ca. 56 inch that may be about right for the fuselage sides, but what about the wing upper surfaces? Wouldn't these be of red-blue only type and a bit larger? And if so, where on this planet can I find some?

TIA, Richard

Whether Type A, A1, B or C, the upper wing roundels for Sunderlands remained at 100" dia (source: Modeldecal transfer sheets), which is 3.63mm in 1/700.  Afraid they don't say (or I haven't recorded) what the fuselage ones should be.  

 

Which roundel type depends on the era but for most of the war a camouflaged Sunderland would have had a Type B (blue/red) upper wing roundel - and certainly at the time HMS Cornwall was lost.

 

PS 3.63mm is a 10.28" roundel in 1/72 or 20.58" in 1/144: you might find something about right on a 1/144 sheet.

Not sure what is correct, but I have a manuscript saying 112" upper wing roundels and 54" on the fuselage.

afair you are both correct.

afair early on the roundel was to be the size of the distance between the leading edge and front edge of the aileron, less 2 inches, at its position of 1/3 the individual wing span measured from the wing tip, or 1/6 of the total wingspan, measured from the wing tip. After the roundel changes in 1942 the largest a so-called B roundel was to be 100 inches diameter
