After email conversation with Mike Starmer I decided to go for Dark Green/Desert Pink/White camo. Mike was very kind and provided me the original scheme from October 1942. The paints are Tamiya, mixing formulas are also from Mike Starmer.
I did masking with Blu-tack and tape. Result is not ideal, but I like it. I feel that the green tone is a bit too dark, but I think I would be able to weather it appropriate way.
