Porcelain insulator made for the Cooke and Wheatstone Telegraph company, which installed a successful telegraph system o the London and Blackwall Railway in 1840 . Four years before Samuel Morse's line in the US. The 1840 line used insulated wire buried underground in pipes. I am asking 50.00 + shipping. Pay Pal as a friend is ok.
