The Parker 61 colours, particularly the 'reds' seem to be frequently misrepresented in pen listings. The 61 only came in two colours that could be described as red, but only one is a true red.
Between 1959 and 1969 the two reds co-existed, they were called 'Rage Red:
And 'Maroon':
There really is only one 'true' red, here are the pencils side by side:
These photographs have not been altered in any way, there really is a huge difference in the two colours. The misrepresentaion usually only occurs one way: a 'Maroon' pen is described as 'Rage Red'.
It is perfectly possible, of course, that this error in description is entirely innocent but, given that the Rage Red colour is the less common, by far, and the apparently irreversible nature of the error there is room for a little scepticism.
For the record, Rage Red was used from 1956 to 1969 and Maroon from 1959 to 1982.
