Tamiya 1/48 Storch - need decals

I messed up some of the decals on my 1/48 Tamiya Storch.

I need the “R” and the “F” for the fusalage sides, and 1 balkan cross for 1 side.

Tamiya-USA says it will take 8 weeks to order the decals from Japan.

Any other suggestions? Any aftermarket that might fit?

Why not mask it off and paint the balkenkreuz? As for the letters you might be able to find a suitable font and print it on decal paper… or you just go buy Generic German national insignia from Squadron or white eagle, etc…
