Vtg 1960’s Electric Portable 49 KEY Pump Air Organ Keyboard Two-Tone

I cannot find any mark, stamp, or label that identifies the manufacturer or model of this organ.
If a I were to venture a guess, I would speculate that it was made in the 1960’s.
It still sounds great.
All keys are responsive and seem to work as they should.
This is built directly into the case, and light enough for easy transport.
Case has a few minor scratches and scuffs, but still looks great. See photos.
