What Lamy model is this?

[larsu]

Any Lamy experts out there? I have been googling wildly to try to find out which Lamy model this is.
The nib says "M 14K 585 Lamy". There is nothing written on the pen itself.

CP1, platinum-coated Guilloche I think.

Thank you, ruby.monkey. Googled it and I'm sure you are right as can be seen here: CP1 PT. Seem to have made a good deal on this one, got it for about €65 at an auction house in Stockholm.
