16800 R 59x,xxx

[temiyasen]

Hi gentlemen,
Read and be member for many years on this forum .
This is my first post .
Now I found a 16800 Matte dial with original paper R59x,xxx from my friend .
But from I read many treads from some forums , most for 16800 Matte dial should be cut off around 1985 or below S/N 9,xxx,xxx and grossy started from 1984 or around ( and somehow overlap with 168000 ).
Is this possible for latest matte dial on 16800 ?
Or any opinion ? Or anybody have this kind of matte dial on R xxx,xxx .
Thanks in advance for any reply .
