3 Vintage Marx ?? O Gauge Locomotive Engines

These 3 engines came from a large box of railroad cars that were purchased at an estate auction for a collector of model railroad pieces. I earlier sold 3 bare Marx locomotive bodies. I'm pretty sure these did not go with those bodies.

There are two electric and 1 windup engines.  I have no way of determining if the engines are good or bad. I do not see any burn marks and and all the engines seem good and tight. The wheels all turn smoothly.

There are no brand names on any of the engines. I'm guessing they may be Marx since the majority of the cars in the box were Marx. There were also some Lionel.

The engines are being sold AS-IS.

Please email with any questions.
