trying to find some rollers older and heavy sliding door

A home owner from Palos verdes Peninsula, Calif. says:
Please see if you can help me find these sliding door rollers.

This is for a 10 ft wide sliding door (each panel 5 feet). The door is bronze in color with havy tempered thick glass and a repairman who came to see the door said, this must be a miller sliding door!
