This would appear to be confirmed by John Crabb having sold the lease of his own house, only a few doors away from the manufactory, on 2nd August 1858.

(Members of the Lachenal family have told me that Elizabeth Lachenal had Socialist leanings! There are a couple of very useful entries for early Lachenal Englishes: 26 Lachenal 9641, sold on 28th July 1862 to Eales for £2.2.0; and Lachenal 7728, sold on 4th April 1863 to Bagshaw for £3.3.0.

It is not until the MDRA for 1863, by which time Lachenal’s advertisement has been reduced to a half page, that an engraving (the first hint) of an Anglo concertina appears (opposite that of an English), with ‘prices [running] from £1.11.6 to £21’.

During the years 1853-1858, Lachenal occupied Alpha and Omega Cottages, British School Lane, 7 Chiswick, as a ‘House’ and ‘Manufactory’ 8 respectively (see Fig. The Chiswick Rate Books show both to have been owned by ‘Messrs.
