Scott held allot of patents...Macdonald Hastings said the date was arguable and I'm sure Scott production dates are somewhat arguable. Is the actual patent date and patentee researchable ?

Pete I read Greener again...is he talking about the top lever of today when he talks of Matthews or something different like a push lever ?
I think that's what Greener is referring to with Westley Richards....a push top lever.
