No aftermarket decals for this models????? how is this possible???

Hi folks

Just one simple question


Why in some very nice models there is no aftermarket decals?, here is a list for example:

1/48 Revell JU 52
1/48 Tamiya He 219 UHU
1/72 Revell He 177 Grief
1/72 Revell Ju 290 Seeadler (second place in 1/72 scale in the FSM “Kit if the year”).

It is because its size?
Lack of reference material?
Not a good seller?

I have found that this 4 kits are excellent and deserve at least one aftermarket decal sheet to dress them up IMHO.!!

So what do you think guys?

Your thoughts……

Thanks!!
