Dates are estimated. Complete set of published 110 maps in Old Series or First Edition. This set is the first systematic survey of England and Wales based on triangulation. It was inspired by the prior Cassini survey of France (see our 5694.000) and the threat of French invasion at the end of the 18th century. The survey sheets were originally published from 1805 to 1870 and frequently updated; our sheets range in date from approximately 1848 to 1870. By 1870 all sheets in the Old Series had been completed (excepting sheet 100, Isle of Man) and thus our set is one of the first complete sets made up of a mix of map states, with the railroads added, which was started in the 1840's. Of the 110 sheets, 54 were issued as full sheets and the remaining 56 as quarter sheets. Sheets 1 and 100 added to set by us (Sheet 100, Isle of Man, was the last sheet published, after our set was assembled, in 1874). Exact dates are frequently ambiguous since old dates were left on in subsequent editions and most editions were not explicitly dated. Our set previously owned by Austrian Archduke Leopold Ludwig (1823-1898) and is from his library with his bookmark stamp. The Old Series actually consists of multiple editions or "states" for the map sheets corresponding to various publication dates; many of these states are characterized in detail in the eight-volume set, "The Old Series Ordnance Survey Maps of England and Wales, Scale 1 inch to 1 mile. A Reproduction of the 110 Sheets of the Survey in Early State in 8 Volumes", 1991, published by Harry Margary, Lympne Castle, Kent, Our map set has no dates (having been previously trimmed with the marginalia) so we have used the Margary work and also the March, 2013, Draft 599-page "Provisional Cartobibliography" an untitled followup publication of the The Charles Close Society to research which edition (date) we have for each sheet and subsequently have written it on the back of each sheet and entered it in the Date field of this catal
