(DIST COMPONENTS PARTS LIST -1949-1959 FORD MPC)

There were no listing(s) for E-CODE DUAL POINT DISTRIBUTORS

 EXAMPLE - FEH-12127-E IS THE DIST IDENTIFICATION NO FOUND ON THE DIST BOWL
                   - B7A 12127-C IS THE ACTUAL FORD P&A SERVICE PART NUMBER

The above information is drawn from the 1949-1959 FORD MPC - FINAL EDITION 

It only represents FORD SERVICE PARTS, not necessarily ASSEMBLY PARTS
or any parts which may have been released in HP KITS or SERVICE LETTERS.

Interesting that the F-code/dual point condenser part # is different from the E-code one.  I found a wide range of electrical values from a grab bag of NOS condensers, all seemingly identical, so the specific value spec. would likely be more relevant than any part # (?). Maybe the dual point outboard mounting is the issue (?).

6 VOLTS/POS. GRD. NW INDIANA

If I remember correctly, the difference in condensers is the length of the lead wire.

I would think the rating is higher as it has to absorb more as a result of the longer dwell time and coil saturation.

My WSM's are buried or otherwise I would find out.
