Removed from an early 80's Remington 700/BDL/223 I bought. I found 'some' data on it but am unsure how/if the info is true:
The following, were the triggers for the 700 and 40XB & 40XBR actions
700-1S Set w/side Safety Right or Left ( Thee Lever Design )
700-2S Deluxe w/side Safety Right or Left...
