Woolwich Foot Tunnel tiles

a correspondent says:

I came across the following in papers for the Newellite Glass Tile Company formed in 1898 and based at 19 Shenton Street, Old Kent Road.October 1912 - "The loss shewn is almost entirely attributable to a contract undertaken by the Company for Tiling the Woolwich Tunnel under the engineers to the LCC."My grandfather held shares in the company and one of the owners, John Tyrrell Newell was a relative of his. The company eventually folded and was dissolved in 1921.I would be interested to know if any record of the contract would be in any archives or if you could point me in any direction to find out more.
