I think DutchGuy has the same 109G14 from 9./JG300 in twice also.  It's the same plane just a different treatment of the wing camo I think.  Looks a lot like a submission meant to be an update that was processed as a new submit.   This situation existed before yesterday's skin release.
I do think it may be unwise to rely entirely on skinners to supply the correct skin reference number.  Players leave the game and come back, upgrade/change computers, email addresses, etc, and I can see how it would be easy to lose track of the reference numbers of skins you've submitted over the years.
Also, if a skinner wants to redo an existing skin which was done long ago by another player no longer in the game, is there a way to find out what the skin reference number of the skin is?
EDIT:  The skins are D/L'ing ingame OK for me, but if I quit game and come back later, they start all over downloading from the first one again (109G6_16.res).   Happened yesterday and again this morning.
There are some real beauties in the batch - love the Marine F4F-4.  Haven't had a chance to check out the others much.
<S> to the skinners and to Skuzzy, thanks for the skins!
