Liverpool optical firm needed a Cooke mount


In Liverpool between 1851 and 1890 the optical company of Abraham & Co traded on Lord Street, Liverpool. In 1864 they ordered from Thomas Cooke & Sons a plain equatorial mounting on a tripod stand. This was for a 4.5 inch telescope.

As an instrument maker I don’t know why they could not provide a stand for this instrument, unless perhaps the buyer had asked for a Cooke mount.

The cost of this mount was £30 which today would be £4,000.
