Parker 61 Green Colours

Some help please.

All my research notes shown only two green colours.
( Have discounted Vista Blue which is a Aqua/Turquoise colour that some collectors think is green )

Surf Green ( 1956 – 1959 USA & Canada )
The ones that I have seen on USA ebay over the years are in average condition and command $150 +

Caribbean Green ( 1959 – 1969 UK)
I frankly doubt the dates are they are correct I would have 100’s of them over the last 20 years. I have only ever seen 2, one NOS the other with cracked shells in very poor condition

There is another green, Mk III Cartridge produced at Newhaven in a solid green ( Not a teal colour ). ( Photograph 2 )

Any comments with any photography of pens would be greatly appreciated.

( Would particularly like to hear from 2 members here who are outside my circle of European Parker pen collectors, one lives in York, the other in the Alps )

Thank you.

I've never seen this before.
cool!

...reminds me of my project to collect all P61 colors - might be harder than I thought it was.

Thanks for your reply.

The accepted dates for the Caribbean green are incorrect.

The one I have is Newhaven made. ( I have full provence for it )

The colour appears to be about 3 or 4 hues darker than a Surf Green

The green Mk III was definitely a production pen, not a prototype colour. ( The colour balance in my photography is not correct, it is mid to dark green )

Have added some photography, the last one is one I was sent by another collector - Surf Green, Caribbean Green & the Green of the Mk III that I have .
