* Change 6 Part Blue {2453 Brick 1 x 1 x 5 - Undetermined Stud Type to 2453a Brick 1 x 1 x 5 - Hollow Stud}
Comments from Submitter:
Until now we only had 2453 and 2453b in the catalog so it is almost certain that all instances of 2453 in set inventories are really 2453a and should be changed now that we have this variant in the catalog.
