Lot 425 G.W.R 1947 pattern double-line block instrument. Probably the best designed block instrument ever used on a British railway. Good, original condition with free-swinging needles and both reminder flaps present. Dials are undamaged but could do with a wipe over with a damp cloth. A slightly later example than the other example in this auction, in a comb-jointed case with a single screw securing the lid.
