The headshell and tonearm chucking lock for the headshell on Victor 7045/7082 is just like on FR 64s and Lustre 801 tonearms. No difference.
I think it’s unique to those Victor arms, and a fine improvement. Only a "small" difference and invisible from outside — though an "end-on" view shows a difference. And they had the sense to use the standard SME h’shell, always available, while others designed their own "unique" shells — they had a firmer grip (screw-down et al) but so hard to find now.
