I don't think writing Stan Jones on a document is evidence of his signature, but you havehelped further the myth David. Well done! 
see latest thread, and see Stan Jones signature on the lab' documents, regarding how he was involved in the introduction of at least 10 spent cartridge cases (DRH/4, DRH/19, DRH/20, DRH/37, DRH/38, DRH/39 (a), DRH/39 (b), DRH/40, DRH/41 and DRH/43) so that the cops could allege the shootings had been a one gun crime!!
