There was no such thing as a 48' 1010, or a 32' 1060, for that matter.

The biggest 1010 was 42.5'   The smallest 1060 was 48.5'.  A cultivator the age of a 1010 48' wide would be a 1050, and one the age of a 1060 but 32' wide would be a 960.  

We have a 1050 which has always been a good tool, but it's no longer applicable to current practices because of trash clearance.  We rebuilt it last winter, adding a bar to the front and rearranging the shanks for more clearance plus replacing the worn out Deere shanks with K shanks.  After a year of use, I consider the project a success.  We hope to find another one to do this winter.
