Coal Sacks (48 per pack). This kit is ideal for your goods yard to provide for the local coal merchant. The kit includes 48 coal sacks, weights, and scales. Initially coal was transported in 12 ton wagons to railway yards. Coal merchants then transferred it to heavy duty 1 cwt sacks for supply to customers. The kit is supplied with pre-coloured parts, although painting and/or weathering can add realism. Glue is required to complete this model.
