The measured building.

type_mark

room_assignment

sheet_scale_paper_inches_per_building_foot

3 in

Paper scale only; not a pixel calibration and not a fixture dimension.

general_cast_fixture_material

Preserve the separate brass-casing note; do not silently turn all constituent metals into a single alloy.

general_casing_spun_canopy_shell_material

general_casing_spun_canopy_shell_default_gauge

20 gauge

Default only. Explicit 16- and 22-gauge P-5 callouts override locally. No thickness conversion performed.

metal_finish_process

Natural bronze highlight color is specified, but no overall patina color or numeric rendering roughness is established.

cylinders_wholly_inside_reflected_half_plan

3 count

Visual count, not a printed quantity or installed fixture count.

cylinders_on_reflected_half_plan_boundary

2 count

Visual count of centers on the cutting/center line, counted once when completing the half-plan.

cylinder_stations_per_type

8 count

Type-level station count derived from drawing symmetry; not eight installed fixtures, and not a survey of the executed chandelier.

Calculated from: p5-half-plan-interior-lamps, p5-half-plan-boundary-lamps

overall_drop

Numeric value unresolved

No legible overall dimension established; upper pipe includes a break, so apparent drawn length cannot establish drop.

overall_diameter

Numeric value unresolved

Not inferred by applying the original paper scale to this photograph.

installed_quantity

Numeric value unresolved

The type drawing and later photograph counts do not establish the total original installation schedule.

Panel note/type evidence only; installed P5/P6 identity, fixture center and anchor height are not accepted.

installed first-floor public-lobby P-5 quantity

Numeric value unresolved

Panel note/type evidence only; installed P5/P6 identity, fixture center and anchor height are not accepted.

Calculated from: light-gate-fixture-type-p5

overall physical fixture diameter

Numeric value unresolved

Panel note/type evidence only; installed P5/P6 identity, fixture center and anchor height are not accepted.
