Up for Buy-It-Now is a new old replacement stock differential ring and pinion gear set, Lempco part number 4734-35  This item was obtained from an old service garage and is not a newly remanufactured part.  According to my vintage manuals, this is used on the following models and years;

1937-1938 Oldsmobile..Models L37, L38, F37, F38 6 & 8 Cylinder
1937-1938 Pontiac..Models P6, P8 6 & 8 Cylinder

 I opened the box for the first time to inspect and take pictures.  The gear set has a 35-8 ratio.  It is in brand new, never used condition and is free of any damage.  The pinion gear has some extremely minor surface rust on it from many years of shelf storage.  May or may not need a light polishing up before installation. The original box is in fair condition.
