So where is the timing tab? Don't see one in the picture the OP posted. If there was a timing tab that was set at the correct diameter to match the "hub" (and the "hub" has a timing line / mark), could the engine be from a low rpm industrial application?
But without a timing tab, perhaps the "hub" is just an old (and cheap) aftermarket replacement for a damaged balancer?
Maybe the OP should check the timing cover for evidense (spot welds) of a timing tab that has been broken off (and some timing tabs were "bolt on" via the timing cover perimeter bolts).

Wherever the OP went, here's what the 1960 balancers look like - one (top photo) is for the low-horse engines, and the other one (bottom photo) is for the high-horse engines.

Another pic here.
The hub has a TDC marked line, I highlighted it in white to be more visible and I added a ruler for fine timing setting.
As for the timing tab on the cover, Idon't have one but two, actually a U-shape plate spot welded on the cover, maybe to accomodate two different diameter hub/damper.
I don't know what is the origin of these parts.

I would suggest that that hub, was used in a stationary, industrial application, like powering a generator, or air compressor, pump, air raid siren, or something else that ran at one RPM, and didn't operate in the natural harmonic frequency RPM range of the motor.
I would be curious what the block stamp pad has on it.

Buy a damper for your motor.
Before you take the timing cover off, you can use a feeler pick to determine if there is in fact a spacer in front of the lower timing gear. I doubt there is.
