WNr and camouflage help for my next model- Bf109K-4, VN+GV at Rechlin

[Mainly28s]

Hi all,
while continuing my builds of aircraft flown by (or potentially flown by) Hans-Werner Lerche, I found that I had a Bf109K-4 in my stash. As Lerche hardly ever specifies his Bf109s, I thought I'd have a go at this sub-type.
I managed to track down that Bf109K-4, VN+GV was stationed at Rechlin, but can't find a WNr so that I can establish the correct colour-scheme. The info about the Stkz is from the list that's provided here by Peter, confirmed by the book "German Flight Test Centres to 1945" by Beauvais et al.
So- what would anyone's guess be as to the WNr or specific manufacturer?

There's a Stammkennzeichen database being maintained at Luftwaffe Research Group but you need to join the group to access it or have someone who's a member look it up for you.

That's where I got the Stkz. Unfortunately, there is nothing about the Wnr or which factory manufactured VN+GV.
