Here is a picture of two bellhousings.

The single wing is for a small 157 tooth flywheel, and uses different bolts to the transaxle. The double wing bellhousing says De Tomaso on the casting, and is for a large flywheel and has bolts on the bottom for the starter plate.

I may have heard a long time ago that somebody in the US cast some repro bellhousings, but I have no idea if this is one. The quality of the single wing is poorer than the double wing.

Again with some great details there Jay!

Mine definitely started life as the two-arm casting, but I am wondering if a changeover occurred at some point and DeTomsao was just "economizing" by smashing off the second arm instead of tossing out "old-run" parts. It wouldn't shock me.

I don't think so. If you look at the ribs, they are totally different, not just removed.

FWIW, I agree w/#2. The section thickness of the right side arm looks pretty thin and fragile. Its believable that an accident at one time or another simply broke the piece off. I've seen another 'Goose where the "removed" arm area on the bellhousing was simply polished. But from porosity pits, one can make out where an arm was originally.
I wasn't suggesting that they were all like mine, only that my car may have left the factory that way. Without knowing the complete history of my car, I have no way of knowing for sure. There is some evidence of prior accident damage elsewhere on it, so it is likely that it was broken off post-factory.

Obviously the second casting Jay shows is quite different in many details and I wasn't suggesting it was the same casting as the two-armed version. Sorry if I confused the issue.
