Temperature and oil pressure gauges for an S2

[Bill]

My S2 project came with SW rather than AC Temp and Oil Pressure gauges. Could these be original?

From what I've seen probably not but not absolutely certain. . I've only seen AC Delco gauges in original cars.

SW gauges were a common aftermarket fitment in North America.  The AC gauges were/are not the most robust so having been replaced is not unusual.
