Details:
Both gears are stamped as being us made. These came to me with a 1966 Chevelle ss396 that was drag car back in the day. The gears could also be used with a 4 series carrier without the spacer. There is some light surface corrosion as shown which will not cause any issues.
There are no chipped teeth or other damage. Both the ring and pinion has a stamped part number of 4094 an engraved 595 as shown. This is a vintage set of us made 4.88 gears for Chevrolet passenger car 12 bolt differential. I am unsure of the manufacturer these gears.
These gears are in good condition as shown.
