Possibly belonging to Obersturmfuhrer Hans Lichter. Only Lichter listed in 1937 DAL. Promoted to Ostuf. 1.05.38. SS nr. 63 688. Member of SD. Interestingly DAL shows that he did not receive TK ring in 1937. Could be mistake or perhaps received ring in '38 and ring was engraved with '37.
Not sure my posts were clear enough, so I write here a summary.
We don't know if that ring is a re-issue, but I am 100% sure that ring was made in the time-frame 1938-1939 (so after 1937).
Maybe the approval for awarding the ring was made in '37 and after that some delay happened... But who knows?
