Honestly, its almost impossible for me to guess..To give a little more potential history on your lip, that would mean it either was purchased new in Europe (I *think* you can do this) or it was brought over from Japan used first or it was brought over on a CTR from Japan.
I know for the longest time I thought CTRs were available for 6G in Europe, but I've since been proven wrong and even seen the parts catalog myself.
So I wonder what the story is for yours.
Oh, and mine.
I'd love to hear suggestions for it.
I suppose I could track down the guy i bought it off, see how he got it and then I could possibly know its origin..
The numbers on the back of my lip/s: I wish there was some way to detect when they were manufactured and could track it down doing it that way, that would be almost too easy...
If there was some sort of tracking number for the oem lips that would make it very simple, but there isnt.. so I feel like its pointless to find out, but for now- its from Japan
