I've got as far as the CofE church heritage record - indicates the West Vale organ was an 1882 instrument (makes sense) by Peter Conacher (Huddersfield, over the hill, also makes sense). The organ in the Baptist church opposite was a Conacher, albeit replated by Rushworths after the factory fire.
So anyone know where Conacher's factory records ended up? Was that not the firm which ended up in the hands of John Sinclair Willis?
