OK this may be a bit long but I think it will work for you.
Go to eBay and do a search for the seller named Bugpiper. Then using eBay send him a message about what you are looking for. He is in Ireland and does a lot of stuff exmilitary. If it can be found he will find it. I was searching for a specific item for about two years and then emailed him and I had the item in my hands within a month. Give a try, what have you got to lose?
