I was assembling an assortment of track in preparation for building a Christmas layout. I grabbed the first two boxes of standard radius track in the storage crate. We see here that even SHS was not sure what they made or they were unsure how to best market it. I assembled a circle for measurement. It is 19” centerline radius, the same as the original Gilbert track. Circles of the two types of track lay right on top of each other.

Tom That's what I found with the 24"/25".

I'm using 19 9/16" centerline radius in my CAD drawings for the 20"R curves. My small radius track is all MTH, don't know if that makes a difference. But I obviously put together a circle a measured it to come up with that. I did it the same day I measured the other radii and they were 24" and 29", that was 3 years ago. However now I'm questioning my results, seems strange in light of the other two...
