The Grand Old Lady of No Man's Land by Dolf L Goldsmith published by Collectors Grade Publications, and as such is generally regarded as the best book on this weapon and goes into huge depth covering all the different marks and contract guns and of course accessories etc. Profusely illustrated, Approx A4 with 568pp. This copy was used in our workshop as a reference when returning WW1 Vickers to WW1 appearance and as a general reference in our company library and is therefore a little grubby in a few places.
This copy is in near new condition (there's a little dust to the top edge) and comes from our company reference library. Photo shows similar book
