Hello Gracious86 and Paul
Welcome from me too.
Paul has said everything really well; but I'll add a couple of points.
The black chaincase screams c1975.
It has been fantastically stored. I do get annoyed with the vagaries
of the market - in not valuing these machines. Correctly maintained,
this will deliver many decades of reliable service, and will produce
a finish equal - or better - to any domestic machine available today.
So, to answer your questions (from me)
History? - as Paul said (history dates back to 1923).
Collectible? - not at the present.
Worth upkeep? - absolutely. Parts available.
Hope this helps.
