https://www.mangaupdates.com/showtopic.php?tid=48837 was locked but there was one inquiry there not addressed so I'll make a separate topic for it.

Information pertaining to this can be seen here:

This list credits 2 works to SaHa

*chapter "I can do it myself?" on 1 January 2015
*chapter 4 on 22 February 2014

I found 2 works on SaHa's site:
*1 January 2015 http://sahadou.com/junk-bros-i-can-do-it-myself/
*30 June 2014 http://sahadou.com/mikami-hokuto-junk-bros/

The first bullet is a clear match to the first credited work.

The second bullet I am less clear about.

Do you guys think that, in 2014, the June 30 work on SaHa's site is the chapter 4 referred to as being done February 22 here? Or are they different?

If different, why is the Feb 22 chapter 4 not on SaHa's site? Does it exist at all?

Is it possible that SaHa released chapter 4 via some other means about 4 months prior to putting it up on his site?

About 100 of the oldest posts on that site have the date 2014-06-30, which is not the actual date that the posts were made. The correct date for the release is the 2015-02-22 as stated on MU

A just ruler amongst tyrants

In case you wanted an explanation as to why the posts are dated that way:

Saha's site was infected with malware for a while in 2014, despite his efforts to remove it. Finally, as a last ditch effort, he purged his entire site and started over from scratch at the end of June that year.

The release posts he made on June 30th, 2014 were for all the releases that weren't included in his most recent batch torrent at the time, to tide people over until he managed to get his direct downloads reorganized and running again.

For future reference, you can often find out more information about old releases by using archive.org to search what the scanlator's website looked like on a date closer to the original release. I'd certainly recommend doing that before seeking to correct the dates of any old releases where the original release post is no longer accessible.

(Speaking of which, your post reminded me of another old release that's had the date incorrectly listed for years now. Might as well try another change request for it...)
