very kindly been given the reference I need by a fellow forum member - thank you!
Mercedes hour and minute hands - 065PZ3753
Bayonet hour and minute hands - 065PZ3753B
Seconds hand for both is 066PZ3754
I have been offered several hands but none are the correct ones so please do let me know if you have something suitable. Do not have to be new - would take old/used ones.
