Blacksmithing Manual Obtain info

Japanese wiki page on this item says the blacksmithing manual could be obtained (or at least, used to be) from the Beginner Gachapon (2012). (To be precise, go to the 製作 ("production") section and on the table underneath, go to the 図面 ("manual", in this case) row. That cell has two sources listed: the "One-Year Thank-you Campaign" and "Malcolm's Random Box". I don't know about the Thank-you campaign, but you can see on this page that "Malcolm's Random Box" == Beginner Gachapon.)

Should that info be added to this page? On one hand, it fills in a blank. On the other, it's not like there's a way to confirm this anymore, since the Beginner Gachapon's done.
