Need help Identifying an old glow engine

[Sigmund Freud]

Old glow engine was given to me lately. Has no markings of model/manufacturer whatsoever and i'm wondering if anybody has any ideas from the pictures I've taken. I'll I currently know is it was once part of a balsa wood boat and has been sitting in a box for 40-50ish years. It has undergone a cleaning since the pictures were taken.

Thank You

It looks like a COX or Testors .049 out of a boat

Is the round black thing a flywheel? It would probably need it to keep it running stable at high rpm.

Wen-mac boat engine? Cox /estes/leisureindustries (ver 6.0) is Google searchable, they have regular big engine glow plugs, or their original style.
