As I wrote before, any standart edge connector from 70's will do the job, gold plated, rounded or not, seems some esb had rounded and other had straight, thin or thick trace, both seem to have been used.
Some years ago as one guy probably found a accurate HP board everyone thought it was a HP, now someone found something close from otis elevator, everyone thinks it's necessary from a otis elevator.
ESB ranch seems to have straight gold and thin trace, ESB R2D2 screen seems to have rounded gold and thin trace, luke blaster portrait seems to have square gold and thick trace, so, it's impossible to know the exact reference, and we can add many boards, computer or so, had different suppliers and different path design even for same generation machine.
so, any green based board with gold contactor, straight trace start(no angled start), quite long contactor, depending on lightsaber, would do the job.
2 first pictures seem to be RAM connectors from old hp stuff, mostly had dozen of 40 or 50 legs black components, some boards have other components.
mostly 3 variations of connectors:
-short square gold, straight trace
-short rounded gold straight trace
-narrower rounded gold, straight and angled trace
I have a remaining complete board somewhere, with wrong connector design, some transistors on it.
got it on fleamarket 15 miles from home, from old hospital.
Last picture is a 70's small american company connector, some are offset:
