From 1932 through 1938 Oldsmobile offered two series: "F" and "L". The Series F came with a straight-six engine, the Series L with a longer body and a straight-eight engine. The Series F was replaced by the Series 60 in 1939. Oldsmobile replaced the Series L with the Series 70. Olds powered these cars by the straight-six and the straight-eight respectively. The Series 60 used GM's A-body, the Series 70 the B-body.
In this interior shot we see line-ornamentation on the inside door panels. An indicator that the interior is original. Water stains are annoying, but the interior is original nevertheless. Rarely restored interiors replicate these lines.
The car originally didn't come with a radio. Tube equipped radios back then were comparably expansive addons. A radio delete plate, as seen here, covers the slot where normally the radio would go in. Later on, a radio was added underneath the delete plate. Also this radio may have become an antique item meanwhile, being 50 years old! - Unfortunately, The Olds' horn button is missing.
Side view:
View from the rear. The bumper is missing.
The paint code lists #20, which is plain black. It proves, Oldsmobile delivered the car in black paint, it is still black and the color is original.
