I’ll compare this V1.2 manual directly against the V1.3 imagery used for the refinement and update the shield again only if it contains clearer or dimensioned geometry.
Compared the supplied V1.2 manual against V1.3. Its estimated shield size agrees with the current 23.75 × 16.96 mm model but provides no additional dimensioned details, so no speculative changes were made; the model remains verified at scale 1 with correct alignment and seating.
