Definitely not any helmet decal I have ever seen.
Looks more like they are for a model plane from the 60s definitely not ww2
Victory flags for allied aircraft model!
I somehow doubt these are for a model aircraft unless its a 1/4 sized model which you won't find many of them around , the size could possibly be used on full sized aircraft beneath the pilots cockpit, for tally on aircraft shot down, but I thought they were usually painted or stenciled on ,perhaps our friend from Jersey could comment to see if he has any ideas
hi guys origionaly there were about 10 sheets of these along with sheets of genuine army decs ,supposingly at the end of the war
