I've recently been trying to get a look at the old versions of Dalek Mod- like Update 36 and others of that time frame. I remember playing that version when I was younger, and I feel it could really benefit the community to have an archive of old Dalek Mod versions for us all to play on.
I can't make an archive myself, but curseforge goes back to U42 or so, and this website has the Legacy version which is Update 39.
John likes his history though, so after all these patches and updates are done, maybe you can convince him.
I'm in the progress of making a list of all Dalek Mod versions if you're interested: https://dalek-mod.fandom.com/wiki/Update_videos
