Used Harley Coil Mount Big Twin 1930-1932 & 45ci 1933-1947 – OEM 31726-30 / 1728-30

Here is a used Harley-Davidson coil mount for early Harley Big Twin and 45ci applications.

Fitment: 1930-1932 Big Twin models (FD, JD, UL, VL, VHS, UHS) and 1933-1947 45ci models.

The Harley-Davidson part number is 31726-30 and the older Harley part number 1728-30.

Looking at the age, finish, wear, and construction, this does not look like a modern reproduction. We cannot positively verify its exact history, so we are listing it as a used vintage part rather than claiming it as NOS or guaranteed original factory production.

The black finish shows chips, scratches, wear, and age throughout, which is exactly the kind of character many builders want on an old Harley. A brand-new reproduction might be cleaner, but it will not have the same decades-old look this piece has already earned.

A good choice for a restoration, survivor, rider, or period-correct custom where using old-style hardware matters.

Please inspect all photos carefully for exact condition. The exact part shown is the part you will receive.
