Eternaween dropage

Eternaweens have been removed from the drop pool for many years now, with the newest timed drop ids being in the 4.3 billions[1] (current ids at time of writing are well into the 12 billions, tf2tools is still down so exact date cannot be easily found but the oldest dragon fury's are 6.2 billion meaning eternaweens dropped well before JI update - iirc they only dropped during 2013 and 2014 halloweens when i was last looking this up while tf2tools was up).

This however, does not mean they are unobtainable. New ones are still being created and are done so via the origin "steam purchase". I believe these are granted to players who pre-ordered Alien: Isolation on Steam before October 7th, 2014. The evidence for this can be seen in a sample of some of the newest eternaweens that are still at their original ids in the following backpacks:

https://backpack.tf/profiles/76561198075667384?time=1648512000
Each of these backpacks has an isolation genuine set along with 2 eternaweens, all of which have sequential or almost sequential item ids relative to each other. E.G. the first link has 2 eternaweens and the genuine set with item ids: 11491562372, 11491562371, 11491562368, 11491562366, 11491562370, 11491562369, and 11491562367. Considering the xeno suit is halloween restricted, valve giving players some eternaweens to go with their preorder bonus makes sense.

It should be noted there are 4 other origins that have granted eternaweens; mvm and surplus loot use the same tables as random drops + the 9 robo hats, unboxed in a crate is already listed in the wiki as being crate 74 expired, and finally the gifted origin refers to the original way of obtaining them through halloween gifts. All of these origins also stopped giving new items at the 4.3 billion id mark.

The barrier for where these gifted items ends (at time of writing) can be seen here: https://imgur.com/a/NrZM7wa where sam's item is in a giftapualt and peacemaker's is a regular item.
