I was very currious about this topic for a long time. I understand the "WHY"... but only to a point! The "SYMBOL" isn't what's "BAD" or "EVIL"... it's what was DONE with AND Who did it!
That being said... I recently found someone on E-Bay that does sell various versions of the Swastika {i.e. black, white, out lined, Etc.} and in various scales and at a very reasonable price.
Here is his link for anyone interested... He goes by "Rebelalpha". Here is the link for the 1/32 ones.. He also does them in 1/48, 1/72 and smaller I think?
Rebelalpha Techmod Decals 1/32 German World War II Tail Markings
This MUST have happened within the past twenty years or so, because I JUST recently bought a {used/opened} 1/32 Hasegawa ME-262,
It JUST arrived today and as soon as I could I opened it, and the Original Decal Sheet is still in perfect shape, and usable! AND the "Swastikas" are still on the decal sheet!
So I would really like to know WHEN, {time wise} that this "Banning of Swastikas on Plastic/Scale Model Decal Sheets" all started to come down?
