Electric organ by Harmona - vintage musical instrument

Description

Beautiful and rare musical instrument, a travelling electric organ by Harmona (Made in Germany, ca. 1960's/70's).
Don't know much about the item itself, it´s been used as a decoration piece for many many years.
The keyboard keys are in perfect working order (springs) and the travel box in great condition.
Seems to have a electrical cable connection but doesn't have the end plug, don't know if anything else is missing but surely a great project to start and get it playing again!
Key to lock/unlock the case is missing.
Any question, please let me know...
Thank You
