-## Summary
+## Source Repository
 
-No canonical upstream repository with Glyphs or UFO sources was found. The only GitHub repository identified was `librefonts/oldenburg`, which is a librefonts mirror containing VFB (FontLab) and SFD (FontForge) source files derived from the original. No designer-owned GitHub repository was found. No METADATA.pb changes were made.
+- **Repository**: [googlefontdirectory-hg](https://github.com/nicholasgross/googlefontdirectory-hg) (Mercurial-to-Git conversion of the original Google Font Directory)
+- **Commit**: `52f780bc9d197280a9f430574e179a5f233c56b6`
+- **Source path**: `oldenburg/src/`
+
+### Source Files in googlefontdirectory-hg
+
+- `Oldenburg-Regular.vfb` — FontLab source (proprietary format, not buildable with gftools)
+- `Oldenburg-Regular-TTF.sfd` — FontForge SFD (likely converted from VFB for TTF generation, not buildable with gftools-builder)
+- `Oldenburg-Regular.otf` — compiled OTF binary (not a design source)
+- `Oldenburgh-test.html` — test file (not a source file)
+- `METADATA_comments.txt` — metadata notes (not a source file)
+
+The primary design source is the `.vfb` file (FontLab proprietary format). The `.sfd` file is a TTF-flavored conversion. Neither format is buildable with gftools-builder.
+
+## Additional Repository Information
+
+- **Librefonts mirror**: https://github.com/librefonts/oldenburg — contains the same VFB and SFD files as googlefontdirectory-hg. This is a mirror, not a canonical designer-owned repository.

 ## Search Results
 
-### GitHub Search
-
-GitHub was searched for "Oldenburg font", "Oldenburg font Nicole Fally", and "SorkinType Oldenburg". No matching repositories were found under a designer-owned account. The SorkinType GitHub organization (`github.com/SorkinType`) was inspected directly — Oldenburg was not among its repositories.
-
-### Librefonts Mirror
-
-The `librefonts/oldenburg` repository was found on GitHub. Its `src/` directory contains:
-- `Oldenburg-Regular.vfb` — FontLab VFB source (legacy, proprietary format)
-- `Oldenburg-Regular-TTF.sfd` — FontForge SFD source
-- Various TTX decompiled binary files
-- `Oldenburgh-test.html` — a test file
-
-This is a librefonts mirror, not a canonical designer-owned repository. The VFB and SFD formats are legacy source formats, not the preferred UFO or Glyphs formats.
-
-### Description Reference
-
-The DESCRIPTION.en_us.html referred to `http://code.google.com/p/googlefontdirectory/` (the original Google Code repository for Google Fonts, now defunct) as the source location, and listed Eben Sorkin (`sorkineben@gmail.com`) as the contact for contributions.
-
-### FONTLOG
-
-The FONTLOG recorded:
-- Nicole Fally completed the design in FontLab VBF (sic) format (9 Dec 2011)
-- Eben Sorkin mastered VBF to TTF (13 Dec 2011)

-## Conclusion
+## Notes
 
-No canonical upstream repository with Glyphs or UFO sources exists for Oldenburg. The sources originated as a FontLab VFB file which was then converted to TTF by Eben Sorkin. The original source is preserved only in the librefonts mirror. No METADATA.pb changes were made.
+- No canonical upstream repository with Glyphs or UFO sources exists for Oldenburg.
+- The sources originated as a FontLab VFB file which was then converted to TTF by Eben Sorkin.
+- The googlefontdirectory-hg monorepo preserves the original VFB source, but the proprietary format limits its usefulness for rebuilding.
+- Confidence in source identification: **High** — the VFB is confirmed as the original design source via the FONTLOG. However, no modern buildable sources exist.
