 ## Summary
 
-Overlock SC is the small-caps companion family to Overlock, designed by Dario Manuel Muhafara of TIPO digital typefoundry (Buenos Aires, Argentina). Both families were added to Google Fonts on 2011-12-19 and share the same upstream source.
+Overlock SC is the small-caps companion family to Overlock, designed by Dario Manuel Muhafara of TIPO digital typefoundry (Buenos Aires, Argentina). The original design sources were found in the `googlefontdirectory-hg` monorepo in FontLab VFB and FontForge SFD formats, which are not buildable with gftools-builder. No canonical designer-owned repository was found.
 
-## Designer
+## Source Repository
 
-Dario Manuel Muhafara operates the TIPO digital typefoundry at tipo.net.ar. See the Overlock investigation for full details on the designer search.
+- **Repo**: [googlefontdirectory-hg](https://github.com/googlefonts/googlefontdirectory-hg) (historical Google Font Directory Mercurial monorepo)
+- **Commit**: `52f780bc9d197280a9f430574e179a5f233c56b6`
+- **Source path**: `overlocksc/src/`
+- **Buildable**: No — legacy formats only (.vfb/.sfd)
 
-## Upstream Repository Search
+### Source Files
 
-Overlock SC shares its upstream with Overlock. The same `librefonts/overlock` mirror repository was investigated. No canonical designer-owned repository was found for either Overlock or Overlock SC.
+| File | Format | Notes |
+|------|--------|-------|
+| `OverlockSC-Regular.vfb` | FontLab VFB | Original source, proprietary binary |
+| `OverlockSC-Regular-OTF.vfb` | FontLab VFB | OTF variant |
+| `OverlockSC-Regular-TTF.sfd` | FontForge SFD | TrueType hinting variant |
+| `OverlockSC-Regular.otf` | Compiled binary | Not a design source |
 
-The `librefonts/overlock` repository (https://github.com/librefonts/overlock) is a librefonts organization mirror, not the designer's own repository. The `src/` folder contains VFB and SFD sources only — no UFO or Glyphs files.
+The primary design sources are VFB files. The SFD file is a FontForge variant for TrueType output. No UFO or Glyphs sources are available.
 
-No GitHub account for Dario Manuel Muhafara was found on GitHub.
+## Family Details

+- **Designer**: Dario Manuel Muhafara (TIPO digital typefoundry)
+- **License**: OFL
+- **Google Fonts date added**: 2011-12-19
+- **Related family**: Overlock (shares upstream source and designer)
+
+## Investigation Details
+
+Overlock SC shares its upstream with Overlock. No GitHub account for Dario Manuel Muhafara was found. The TIPO foundry website (tipo.net.ar) does not link to any source repositories.
+
+The `librefonts/overlock` repository (https://github.com/librefonts/overlock) is a librefonts organization mirror containing VFB and SFD sources for both Overlock and Overlock SC. It is not the designer's own repository.
 
 ## Conclusion
 
-No canonical designer-owned upstream repository was found for Overlock SC. The shared upstream with Overlock provides only VFB and SFD sources via a librefonts mirror. No METADATA.pb source block was added.
+The original design sources for Overlock SC are preserved in the `googlefontdirectory-hg` monorepo as VFB and SFD files. These are legacy formats not buildable with gftools-builder. No modern sources or canonical designer-owned repository exist.
