I know tf2unusual has a craft number search, but that only seems to cache whoever had it when the site trawled their backpack.
I know the outpost has a now working craft number search feature, that would only bring back the craft number if it found it, and if it were in a trade, which is all dandy, but I was wondering if there were a way to search for any item in a trade matching a specific craft number.

Thanks :)
