They are pretty hard to find I'm afraid. Maybe you can contact Henrik from
http://www.henrikc.dk/camouflage/, (email on bottom of page) an avid camouflage collector living in Denmark. If he can help you, I'm sure he will point you in the right direction.
By the way, what happened to Gordon Schumacher? He doesn't reply to his mails anymore and his eBay-shop has simply vanished. Anybody know anything more? I hope he resurfaces cause his Kommando Shirts in M90 and M84 should be available later this month. (although I'm going to get the tacupgear.se field shirts in M90 and M90 desert)
