In 1960, most Sectional Appendices were reissued. However, as Swansea Area had been reissued in 1958, there was, it seems, no 1960 reissue thereof. This gives rise to a query about the above section of GWR line which was (for some reason) hitherto included in the Oswestry Area (Cambrian) Appendix. However, the 1960 Shrewsbury book ends at Aberystwyth and states that the Swansea book should be consulted for the above stretch. My question is therefore which edition of said book is meant?
