348/308 Misaligned Milometer Digits

[Petercr]

In my viewings of 308/328 cars I've noticed a few cars with misaligned milometer digits, usually the first two digits

Should I consider each to be a case of clocking or is this form of failure common ...................I see several cars have had their milometer units changed out, presumably due to failure of the original unit, but I'm not sure what form that failure takes.

Comments appreciated
