I've part 31464 in yellow *without* a sticker. The part came in yellow in
set 991144 which I purchased in 2006. Set 991144 was released in 1998 and 2002
according to the label on the box. On the label the part is shown in red. The
part color in the 1998 release might have been red.
Please merge (meaning delete from the catalog) these items:
[P=2961stk01]
[P=9127stk01]
Reasons:
1. The parts list on the set box for 2961 shows the sticker already applied from
the factory.
2. There are several expired auction records online that show photos of both
sets in new condition. In all instances the stickers are already on the mirrors.
3. BrickLink has no image of either sticker sheet.
4. Part 31464 is not currently available for sale without stickers.
If it is proven in the future that these sets came with sticker sheets, then
they can be added to the catalog. Until then, there is no proof for sticker
sheets and a reasonable amount of proof against.
Once the sticker sheets are deleted, some additional catalog/inventory work will
be necessary to clean up.
