The plate below is the only pre WW2 pattern used by Horwich apart from Rebuilt. These builders plates are always brass and were fitted immediatley after the grouping to all new LMS locos including those L&Y locos on order at the grouping.
Size in inches- 10 & 3/8ths by 5 & 15/16ths (hole centres 8 & 3/4 typical)
Pattern Rarity- Common
Special Features- Retains all of the characteristics of the MR Derby styling, an almost perfect clone of the Derby plates. Note on the example below the two raised spots near the bolt holes left from where the pattern was lifted from the sand.
