Marx Vtg O Gauge Train x4: Wind Up Engine + Key, Coal Tender, Box Car, Caboose

Louis Marx Co. Vintage O Gauge Train Lot of 4 Pieces. Lot includes (1) black wind-up locomotive engine with the wind-up key (plastic outer cover with metal inner gears), (2) black Union Pacific tin coal tender car, (3) red tin Seaboard box car/open top gondola, (4) yellow tin Union Pacific caboose. All hook together. Marx started making these type of trains in the 1930s, but I'm estimating that these were likely made in 1950s or 1960s, mid century time frame. Pre-owned condition. Engine does wind properly and works - it does stick a little and may need to be nudged after winding (maybe it can be oiled?). There is a little rust on some of the metal parts. Also, I'm unsure if it is supposed to have a back panel. All of the tin cars have scratches and scuffs and may have some small dents. However, the graphics and overall painting still looks great.
