Superman #127 was published by KG Murray c.February 1958:
The main features are as follows:
The Man with the Zero Eyes, originally published in Superman #117, November 1957
The Trial of Jimmy Olsen, originally published in Superman's Pal, Jimmy Olsen #20, April 1957
The Secret of Fort Superman, originally published in Superman #117, November 1957
This issue contains two full-page filler strips. The first is a Peg strip on the inner front cover, originally published in A Date with Judy #17, June-July 1950, however the print in this issue is likely related to the reprint of this strip in Girls' Love Stories #45, January-February 1957. The inner rear cover contains a Professor Eureka strip originally published in House of Mystery #64, July 1957.
I have not identified subsequent reprints of any of these features in other KG Murray issues, but I will not be surprised to find some or all are in undocumented issues of Colossal Comic or Superman Super Library.
