Engine Revs seem high, could the tachometer be wrong

Hi
Had to remove the cluster on the 320 to put some new gears on the speedo and notice the date on the cluster is 27/03/92 so not a 1988 original cluster. Got me thinking that maybe it is from a 318i and this is why the rev counter seems to read high (3200rpm at 50mph and ticks over ar 1100rpm). The code plug has BMW18 1385364 which according to a 2017 post is for a 318i. Can someone just confirm this and the Speedo rpm readings fr me before I start to try and sort this out.
Thanks David
