Didn't we go through this ones before? I could have sworn...

I take it you don’t have the Graf & Grislawski book? I still think that will be your best source. If it's too expensive, sell some more prints

Seriously, I think I've posted this stuff so it's probably old news but...
A Portuguese (?) website that lists Green 1 as being W.Nr.15913-

An early Claes Sundin profile, no W.Nr. listed-

Two profiles from the Graf & Grislawski book by Sundin-
(I'm sure you've seen these Jester

)

It's pretty easy to surmise that information on the color of the fuselage number must have come up in the preparations for the book

Without the book, I think your best bet is to try here-

Not sure what section of the forum you should ask your questions on but someone there will know the answers
Almost forgot, I think you should knock back the happy hunter badge, it looks like it's trying to be in front of the wing instead of on the fuselage. Maybe tone the colors down? You'll see Claes has a similar problem on his.
