A flea market collection includes 2 part 95 Sprocket Wheel 2in 36 teeth along with a very short length, 6.5” of matching chain (and a matt black 96a 14 teeth). The Nickel one has Meccano stamped thrice round the centre, 2 facing inward and one outward. It also has 2 holes that OPM says it shouldn’t have. The boss is nickel plated. The red one has no mark of origin, and the boss doesn’t look quite like I think a Meccano one should; however the teeth of them match quite well.
