[Super]

I have had many E3 Komachis both the grey and yellow wheeled bought in large lots that were yellowed and in a strange way. Yellowing is not consistent as it could have yellowing on one side or a darker shade on different areas. The original JR Kyushu 885's has the same yellowing problem. We have had many discussion here about the causes of yellowing with no definitive answers from what I remember. So many different theories.
