Identify Flywheel

Can anyone identify this flywheel for me. It appears to be a Model T flywheel, but it has the high ring of metal around the outside in place of the spacers/spools for the magnets. Was this ever issued from the factory? Was it an old time modification for something that did not run with magnets? Maybe used on a Ford Tractor or stationary motor?

I will try to get one of the other side tomorrow, but I think it looks like a standard flywheel.
It is tomorrow and I am editing this message to add the photos of the other side of the flywheel.

Its T. looks like a another ring gear with "most" of the teeth removed. Humble hands of home.

It’s a modification for extremely low speed idle and to improve low speed running. Adding that additional amount of weight at the outside of the flywheel will allow a T engine to idle very slowly and crawl along without bucking. Probably was in a parade car or someone who liked to show off super low idle.
I plan to do something similar when I rebuild my T stationary engine. I’ll be using a heavy machined bronze ring the outside diameter of the flywheel under the magnets instead of the aluminum spools. It will add several pounds of rotating weight to the outside of the flywheel without removing magnets or effecting magneto operation.

T-701 C is the Factory Number for a 1919 to 1927 Flywheel, so that one has been modified for some reason.

Speedytinc,
" Your most of the teeth removed" is standard and is to allow the starter pinion to mesh with the ring gear.
Adam,
The flywheel would be heavier with the standard magnets, a lot heavier than that ring. It is most probably there to hold the starter ring gear in place. ( Starting torque on a high compression engine and with 1/4 brass screws may fail ).
I feel that the flywheel assembly has been lightened to allowed for high engine RPM as for a speedster with an oil pump system for lubrication....n

I would wager the ring probably weighs more than the magnets. Even if it weighs the same as the magnets, 100% of the weight is at the very outside rim of the flywheel which is dynamically way more than the magnets weigh.

Some clever soul did that to increase torque. It would be good in a truck, doodlebug, or stationary power unit.
