also this:http://mangasee.me/manga/?series=Bleach&chapter=535&index=1&page=12 First, Isshin's, and Masaki's, souls were linked together by Kisuke, that's how Isshin knew how Masaki had died, and not because Isshin had active Shinigami powers.

Secondly, I don't see how that charm proves that Isshin had active Shinigami powers at that time, since Isshin told Ichigo that he got the charm from Masaki, and not that he made it himself. Should we speculate that Isshin was lying, then it's more likely that Kisuke, or Ryuken, gave Isshin the charm to protect him after his Shinigami powers had been sealed, or that Isshin asked Kisuke, or Ryuken, to make one for Ichigo, when he learned that Ichigo had Shinigami powers and was out fighting Hollows on a daily basis.

On the next page, following the one you linked to, Kisuke informs Isshin that: "While you're inside the shell, you will never have access to your Shinigami powers. That includes the ability to see Hollows." Since that is fact, and the assumption that Isshin made the charm is speculation, then I trust the fact.
