Part 61791 (Kanohi Crast) has the alternate ID 85800.
Part 64258 (Gresh Helmet) has the alternate ID 88896.
Both of these are used for their respective non-marbled parts, and appear on
Bricks & Pieces (and subsequently Brickset). Sets 8995 & 7117, respectively.
[...] BrickLink uses moldnumbers. Both parts show one PCC, which is the same on BrickLink and Brickset. Do you have these parts and do they have different numbers molded? Diana (12 months ago, Jun 5, 2023, to Catalog Requests)
