By the way, they should not be aluminum.
The original frames were cast in ZAMAC and Ted described his as being "zinc". ZAMAC is largely zinc (around 95%), I guess that is what he used.
There are a number of different grades of ZAMAC with different characteristics.

Not likely.

I think one would have to compare a few of the frames to an original Lionel one. Verify correct dimensions, size & placement of the holes / slots etc. I've had the bad luck of purchasing some reproduction parts in bulk that turned out to be worthless because they were not made correct. But I think those parts were ruined after being molded / cast. The holes that were bad were drilled, not cast in place.
