R5 Gauge Identification

[AAAltered]

I was rooting through my box of gauges to see if I was running my "best" ones.
I realize that although all mine in the box have straight shafts, there are several differences.

Speedo:  I have both "120" mph and "100" mph.  Which is right for the R5?

Tachs:  All are 8k redline and 10k max.  However the fonts are visibly different.  I notice that one style has "Nippon Seiki Japan" across the bottom and the other doesn't.

Anyone know what's what?

120 is correct.
