7 Speed XT cassettes

Is there any difference between an HG90 and the lesser ones like HG70 other than the colour of the lockring? NOS seems to be at the £100 level.
The STX SE from 95 used a different stamping with larger cutouts and is about 40g lighter.

How are the lock rings different? Both of mine are bolted together with chrome lock rings.

The modern cassettes are lighter too.... but they’re not retro :lol:
