New York Button Help

Would like some information on these two buttons I have , look like silver over brass Knights head my problem is the writing on reverse.Says Harris & Nixon New York but I cant get past Presidential badges and other memorabilia because of the names. Found another similar button but only has the Nixon name and New York.Would anyone have a date possibly for this type of button.

 

I couldn't find any either!! Being linked together, might they be cufflinks???
VERY cool!!

 

Just linked with metal ring like you do with keys, found a couple examples with Nixon and New York on them seem to be uncommon.

 

Hmmmm
