John;
At least one vote has been cast that the cars left the factory all of one flavor, but in the intervening 70 + years just about anything could have been done to your car.

Back to the differences between the two distributors.

AutoLite:

Vacuum chamber linkage is external.

When vacuum is applied distributor rotates. Breaker plate does not rotate within housing.

Hand pressure should be able to rotate the distributor. Rotate in the direction that vacuum would pull the linkage.

Wire from coil attaches to a screw external to the distributor

Delco:

Vacuum chamber linkage is internal.

When vacuum is applied there is no external movement. The breaker plate rotates, not the housing.

Distributor is rigid, hand pressure will not rotate.

Wire from coil attaches to a binding post and is held with a nut. There is an insulator that supports the binding post as it passes through the casing.

I'm not completely sure about the differences between the breaker sets, but I believe they are:

AutoLite: The breaker set has a distinct 'boomerang' shape. The pivot point, hold down screw, and adjustment screw are not aligned.

Delco: The breaker set is much straighter. The pivot point, hold down screw, and adjustment screw are almost aligned.

Please post a photo with the cap and rotor removed.
