Abstract
The Campbell Boat Company was a boatbuilding firm in Holland, Michigan, Ottawa County, established in September 1937. The company was located at 1691 S. Shore Drive in Holland in a new factory. The company built a small addition to the plant in 1938. In addition to boats, the company also did some steel fabricating. Kenneth H. Campbell, formerly of Calumet, was owner of the firm; H. C. Reynolds was general manager. In 1946, the company had a workforce of 35 males. The company employed only five males and one female in 1950. The company presumably went out of business in about 1953. Collection includes a 1930s photographic slides illustrating wooden sailboats and steel boats being constructed inside the company and boats being launched and sailed near the company’s site, copies of original blueprints for a 1938 building addition (See Hope College Oversized), and biographical materials on Kenneth Campbell, including his personal copy of The Mechanical Engineers’ Pocket-Book: A Reference-Book of Rules, Tables, Data, and Formulae by William Kent (1916).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
