Got this from organforum.com...
"The M-100 series succeeded the M-3. It has all the features of the M's plus
reverb and some presets. It is the last tube spinet model Hammond made. It
was replaced by the T-100 series which IMHO is the best spinet organ ever
made (until they screwed up the vibrato.)
BTW the second and third digit of the model number denotes the furniture
style and finish; second digit (1)=Traditional; third digit (1)=Mahogany.
Few spinet organs have any value today regardless of manufacturer or
features. However, there are still a few out there (like me) who still
appreciate that many spinets can be fun to play if you don't mind doing
things yourself. (There are no automatic play features on the M-100!) The
Hammond spinets (which were just scaled down versions of the consoles)
usually produced a fuller, more pleasing sound and were more reliable than
most of the competitors of the day. Also they cannot go out of tune."
If it's in good playable condition and doesn't need too much work, it's a good starter for your kids...
