On the following coaches the first class stripe extends along the whole length of the coach (and round the ends).
Roco 44753 (Rev 10.09.86),
Roco 45860 (Rev 12.04.72)
Piko 59620 ( Rev 29.10.73)
This style matches a pic in the EJ magazine “Die V180 der DR” of a Gp61 Am in the D243 dated 20.04.73
I also have found an image of another Gp61 Am in the D115, again with the full length stripe dated 02.05.71.
But the recently released Roco 64646 has the stripe between the doors only. I believe this has an early 70's Rev date but not certain.So, are both styles correct for the early 70's or is the shortened version more appropriate to a later period?
