I found some washers that look pretty nice. They are just zinc plated
but not much of the washer really shows.
They are 0.470 ID x 0.656 OD x 0.030 thick
They are just slightly larger than the 112A switchcraft washers.
0.460~0.465 ID would be about the smallest you can get on these jacks
so the 0.470 fit reasonably snug.
I don't know where they came from originally but I can try and find
out. I put a photo up in the photo section. You can see some slight
scratches caused by the larger washers. They're pretty minimal unless
you get the light just right.
