what are multi-beaded fences?
 

thanks in advance.

BH and higher grades have a beaded fence. BH and AH have a single bead while AAH would have 2 or more and A1S is likely to have 3 beads.
The bead is the raised rib at the rear of the breech balls of the frame.

For illustrations of these see the Identification and Grades sections of this site.

i see. its the grooves(engraved lines) that are filled with gold on some. right?

A frame before and after the addition of beaded fences.

AND back to mine again...it appears mine is only 2, making it AHE fencing, not A1S. someone didnt know their parkers.
