* Change 2 Part White {3940 Support 2 x 2 x 2 Stand with Undetermined Hole Type to 3940b Support 2 x 2 x 2 Stand with Complete Hole}
Comments from Submitter:
It's been over a year now since this part variation was introduced to the catalog and the pattern is quite clear. The B version of this part emerged in the late eighties and there is no evidence of the A variant in the nineties through to the present day.
