There is a funny thread at Klickywelt (log-in required), discussing how this part was available at the DS/parts service for exactly one day (I may be off by a day or two) before it was pulled, presumably because of high demand...

Hauden-Lukas said in that thread he had his order reduced from 5000 to 500 pieces... or was he joking?
Other people said they had ordered 999 (probably a joke, the post included a 'giggle' smiley), 20 and 15 respectively, all unsuccessfully.
Only one person had received what they ordered.. 9 bearskins.
If people are really ordering parts in the hundreds, its not surprising the stocks run out so quickly! It makes me wonder if it is collectors which provide the biggest share of the demand for spare parts.
