Are gearboxes from previous years legal?

[SuperBK]

We some some gearboxes from previous years, and I was wondering if they are legal to use. My interpretation of the rule is Yes, since they have not been modified:

<R29> COTS items from ROBOTS entered in previous FIRST competitions or COTS items that are no longer commercially available may be used under the following conditions:
A. The item must be functionally equivalent to the original condition as delivered from the VENDOR (e.g. a part that has non-functional label markings added would be permitted, but a part that has device-specific mounting holes added would be prohibited), and
B. The item must satisfy ALL applicable 2011 FRC materials/parts use rules.
