Hi Gary: Not to steal your thunder but here's how I did mine. I know it's the incorrect 4 color lozenge pattern vice the painted on, but with the blue over it, I don't think it's that noticeable other than there is lozenge under it.
I used an old Aurora Lozenge pattern, enlarged it to 1/32nd and with carbon paper traced the pattern over the base coat and then hand painted the pattern. Once dry overpainted it with blue until I was happy with the result. Were I to do it again, which I probably will as I have this kit, I would blow up the lozenge pattern using the scheme of "White 4, Schlasta 25, from the first release of the Hannover, kit# 32024, which is still up on the WNW website, and use that as a template for the lozenge to either transfer with carbon paper or use as templates for masks.
Good luck and looking forward to seeing how you go with it.
