Mammoth selection of GWR and later Maps & Plans well worthy of sorting. Areas of interest are Wiltshire and Gloucestershire. Condition varies so be careful when viewing as there are some dated early 1900's that are a little fragile. Also a box of GWR Water Supply documents for various locations within the GWR. Additionally, qty 3 Rhymney Railway Plans & Sections dated November 1907. An extremely extensive lot.
