What should a Chang Jiang 750 lineage claim show?

The Chang Jiang 750 workshop treats a familiar lineage story as a set of questions to check. Similarity between machines is not, on its own, a complete documentary chain of technical transfer.

Explore the object workshop at /china/cj750; use /method to distinguish documentation from inference.

Discussions often place the BMW R71, Soviet M-72, and Chang Jiang 750 in one sequence. Each link needs its own dates, documents, technical comparisons, and production context. A statement about resemblance is narrower than a statement about an uninterrupted transfer archive.

A responsible account distinguishes surviving evidence for an object from an inference about how a design moved between institutions. It also separates a later production change from an original design relationship.

Which drawings, approvals, factory records, or dated objects support a specific step? Are model names applied consistently across sources? What is directly documented, and what is inferred from technical features?

If a primary document cannot be inspected, the answer should say so. The workshop is a starting point for examining these questions, not a substitute for missing records.
