Share 'Adams and Co. Camera company question'

Does anyone have information on some of the products made by the Adams and Co. Camera company of 26 Charring Cross Road, London? I collect early exposure calculators, actinometers, etc and I've found a reference to a Telemeter made by Adams and Co. Looks like a telescope, but it has  "The Adams Telemeter, Adams and Co. 26, Charring cross road. London W.C." and it has an engraved distance scale…
