The only thing I can remember about Viscount Aerospace bikes is that they were originally called Lambert's and the tubing they used was called 1027. They later became Viscount and finally Trusty and I am sure that Yamaha were in the plot as well. The two other things I can remember is the loverly blonde sort in hot pants and brown boots who use to advertize the Gold Plated Lambert model. Oh and another loverly blonde sort who rode a Brunswick green Claud Butler with those alloy Lambert forks. She use to p--s pass me everyday on her way to work. Hinds got hold of all the old Lambert stock hubs, pins, brakes, forks etc. There is a shop near to me with a load of NOS Lambert alloy brake levers.
