C 53Edit

Could you confirm what domain you want for "C 53"? The designation appears in several contexts (for example, as an entry in the Encyclopaedia of Chess Openings as ECO code C53, as a military aircraft designation like C-53, or as a chemical or catalog code). Once you specify, I’ll draft a neutral encyclopedia-style article with appropriate headings, include encyclopedia-style links, and end with a See also section.
