it's not always easy to know unless somebody writes down ALL the details from the original machine when booting up.
I'd say in at least 95% of cases the actual drives for these things have incorrect labels on because drives were updated with software updates and the labels never changed, so even in cases where the chd has a date in the filename it might not be accurate for this reason.
Even in MAME several were mislabelled for many years because it was assumed the drive label was correct and nobody checked service mode.
