What vintage moog has 37 keys?
Or was there never a 37 key?
1974 pratt reed keys? No it does not have the board its from some old something.
This has 36 keys, no?
Don’t recognize it.
Flip it over and post a picture of the underside.
It’s a lower manual off an old organ - probably a Hammond… 
Definitely not from ANY Moog whatsoever.
And not likely to have a contact system that will work with a synth either. Not the first time I have seen keybeds ripped from organs and flipped as “synth keyboards”.
who said it was being flipped? I was going to pull the keys and parts but if it was something rare I did not want to ruin it.
Now being sold as octaves but thank you for the info.
