Hs{Lord Ernest Hives - Chair}/Wst. 86118 BY/4/G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 30.5.33. 20/25 HP. CHASSIS - MAKE & BREAK LEVERS. WST Referring to Hs{Lord Ernest Hives - Chair}/Wst.3/MA.23.5.33. I did make the suggestion you referred to of using a brass bush instead of phosphor bronze for the pivot pin to work upon, but had overlooked the fact that in order to get the brass sufficiently hard to represent a reasonable rubbing surface it would be too hard to spin over ascalled for by the design.
