Jac's are the easiest of all classics to get. I believe 3-4 have gone to sale in the past year here alone. If we want to talk rare lets talk about the khc maverick, the asahi 249 or the ftc specter I once had in my collection. You also aren't the most easy to talk to person yourself.
The difference between other classic users and you is when something is wrong with there gun they state it. The jac m60 I had had all things wrong with it listed and I spoke with the buyer in great length about it and the defects. Only then did I take his money.
Being as how you just drive the guns across from the states its not like your some kind of savior of the classic users. You have also had problems in the past with other users. Perhaps you should try and hike up your shorts and take the fault like a man.
