  Is a scientific research paper based on (i) public, online observational data
files and (ii) providing free-licensed software for reproducing its results
easy to reproduce by the same author a decade later? This paper attempts to
reproduce a cosmic topology observational paper published in 2008 and
satisfying both criteria (i) and (ii). The reproduction steps are defined
formally in a free-licensed git repository package "0807.4260" and
qualitatively in the current paper. It was found that the effort in upgrading
the Fortran 77 code at the heart of the software, interfaced with a C front
end, and originally compiled with g77, in the content of the contemporary
gfortran compiler, risked being too great to be justified on any short time
scale. In this sense, the results of RBG08 are not as reproducible as they
appeared to be, despite both (i) data availability and (ii) free-licensing and
public availability of the software. The software and a script to reproduce the
steps of this incomplete reproduction are combined in a new git repository
named 0807.4260, following the ArXiv identity code (arXiv:0807.4260) of RBG08.
