B-block staging entry validated for model fit. Imported from staging batch duell-thimm-b, source entry 231. Retitled from long descriptive title; semicolons are intrinsic to the work.
Gelli treats the H. B. volume as part of the Blackwell family but prints 1780, whereas the established local Thimm witness remains 1730. Preserve the work and record Gelli's date as conflicting secondary evidence only.
Castle also records the 1730 London Blackwell witness with six woodcuts.
