The short B-block cross-reference and the full R-block component describe the same 1877 Paris edition and were consolidated here.
R-block staging entry validated for model fit. Imported from staging batch duell-thimm-r, source entry 1738. Retitled from title with extended descriptive subtitle.
Gelli transmits the same anonymous-initials fencing manual under A. R. and appears in the current OCR pass to read the year as 1887, but both the existing Thimm witness and BnF catalogue tradition point to the original Paris edition of 1877. The local record therefore keeps 1877 as the more credible publication year and stores Gelli's divergent reading as source-variance evidence.
