Lot #188682: 3 Vintage 150 Ohm Railway / Telephone Signal Relays – Wood & Cast Iron Bases

- Group of three vintage electromagnetic signal/communications relays or related switching units. Each features twin electromagnetic coils, adjustable contacts, brass hardware, wood mounting board and heavy cast metal outer base/frame. One unit is marked "150 OHMS." Period inspection/repair markings are visible on the reverse, including "SIG. SHOP JULY 1960," suggesting these were maintained as part of a signalling or communications system. Interesting examples of early electrical, railway signalling or telecommunications equipment with substantial original mechanical and electrical components. All three are untested and working condition is unknown. They show age-related wear, oxidation, surface corrosion, dust, old cloth-covered wiring and evidence of historical servicing. No attempt has been made to clean, polish or restore them. Includes all three units shown. Please review photographs carefully for markings, construction, completeness and condition.
