Was doing some additional search criteria and saw Ele made a similar post to this (thread now closed):
http://www.project1999.com/forums/sh...light=jorlleag
He posted a bunch of screenshots, didn't happen to notice specific links to dates on sites... was it found that his info was insufficient and needed more data or is it decided not to bother with implementing the pre-upgraded version of weapons to ToV?
I would be happy to research more for specific dates / wayback links / patch notes if that is what you need, but wouldn't waste my time if you were not interested in implementing the older items into the timeline.
