Extraction: Reviewed · extraction partial. Partial timed visual review: Partial first-pass review from catalogue/OCR then one 1000px JPEG locator derivative of public/archive/drawings/complete-upright/IMG_1088.webp. Regions normalized in unrotated access image; actual principal text is upright (0 degrees). Small blurry values remain unresolved; no modeling authorized. Partial timed visual review: Source-local drawing evidence only; installed quantity, accepted world placement and physical geometry not established. Partial timed visual review: Pipe rail nominal specification reading only; actual outside diameter and installed geometry are separate properties. Partial timed visual review: Truck note reads BRONZE SHEAVES, independently contradicting prior MONEL transcription. History retained; separate resolving text and numeric candidates only. Pole note prints bottom/top diameters. Partial timed visual review: Source-local specification only; installed placement, quantity and physical geometry remain unestablished. Partial timed visual review: undefined
