Wheatstoner Posted June 13, 2013 Share Posted June 13, 2013 I was researching an Wheatstone concertina in the Horniman ledgers and noticed the designation "S.V." then "W.S.". Does anyone know the meaning? Thanks http://www.horniman.info/DKNSARC/SD01/PAGES/D1P0750L.HTM Link to comment Share on other sites More sharing options...
Geoff Wooff Posted June 13, 2013 Share Posted June 13, 2013 (edited) S.V. stands for Slide Valve (or Side Valve) or some word like that, and refers to the air release key being a little lever that is moved sideways to operate, by ones thumb on a English. Later on this can be K.V. meaning Key Valve when they started using air buttons. W.S. stands for Wrist Straps.... désignâtes that the instrument was fitted with these.

Myrtle's cook Posted June 18, 2013 Share Posted June 18, 2013 This is really helpful. One cannot help noticing that there are quite a number of other abbreviations used in the ledgers. Some seem to mutate/shift over time (and perhaps by clerk) as Geoff notes with SV and KV. A full glossary of these abbreviations would be really helpful. Has someone already compiled one and put it in the public domain - or is this a piece of work waiting to be done? Link to comment Share on other sites More sharing options...
