Also Mallory made the 2301105 for Model A spark curve.

And 2301106 for Model B engine.

I have single point version and a dual point version of 1105.

Both of these have spring sets and user adjustable weights and stops to setup the curve and max advance.

I have a copy of instructions that explains the setup on the house computer.

NOTE I am not at the house to check the part number just now.
