The year is spurious for Russian Empire, and four digit number has to be year, right?
The second digit is the problem. What digits can be definitively eliminated? 1,2,4,5,6,7,8,9
Meaning it`s either ``3`` or``0``.
If it`s 1086 we have Hijri year 1675 or Iranian Calendar (Jalali Calendar) 1707, which is impossible.
If it`s 1386 the maker was honest, indeed. Made in 2007.
