The default theme and theme name of ‘slim-service’ are defined in (gnu
services xorg):

--8<---------------cut here---------------start------------->8---
(define %default-slim-theme
  ;; Theme based on work by Felipe López.
  #~(string-append #$%artwork-repository "/slim"))

(define %default-slim-theme-name
  ;; This must be the name of the sub-directory in %DEFAULT-SLIM-THEME that
  ;; contains the actual theme files.
  "0.8")
--8<---------------cut here---------------end--------------->8---

The ‘artwork-repository’ variable here comes from (gnu artwork):

--8<---------------cut here---------------start------------->8---
(define %artwork-repository
  (origin
    (method git-fetch)
    (uri (git-reference
          (url "git://git.savannah.gnu.org/guix/guix-artwork.git")
          (commit "61ae7c8")))
    (sha256
     (base32
      "102fxk2l6b0ibry3n430q8ljhwrnbml9qgalzkz6v09r7sx6a532"))))
--8<---------------cut here---------------end--------------->8---

To use the “GNU” SLiM screen, you need to use an older revision of the
guix-artwork.git repository.  So, in your OS config file, you can write
something like this (untested):

--8<---------------cut here---------------start------------->8---
(define %old-artwork
  (origin
    (method git-fetch)
    (uri (git-reference
          (url "git://git.savannah.gnu.org/guix/guix-artwork.git")
          (commit "3236581")))  ;pre-GuixSD branding
    (sha256
     (base32
      "0ayg0693agck8zkcxfymph5ccc3y44cdf9i4y0qvxajhac8rkcaj"))))

(define %old-slim-theme
  #~(string-append #$%old-artwork "/slim"))

(define %old-slim-theme-name
  "0.8")

(operating-system
  ;; ...
  (services (cons (slim-service #:theme %old-slim-theme
                                #:theme-name %old-slim-theme-name)
                  ;; ...
                  )))
--8<---------------cut here---------------end--------------->8---

HTH!
