I love the vintage runners, electrical or steam.
Yours looks in nice condition. Where has it been
over the years and what stories it must have.
My parents had an antique shop in the 60's and
that is where I get my love of vintage. Goes with
my degree in history.
Anyway, there is on EBAY USA a 4-solenoid motor
(it is electric) done up quite well. The listing title
follows:
'Steam Engine Design Cartrol Solenoid Engine'
Good Luck,
