Being a tach from the late 60's early 70's and going up to 8000 RPM I would assume this thing is for an outboard two stroke. Most similar automotive gauges from the same era that I have seen only show 5 or 6000 RPM. Mostly 5000. Hopefully someone else will chime in on this soon. You could also try some classic boating forums to see if they know what it is.
