Hi, I''m surprised you''ve had no response. Dr. Hanneman is getting on in years and he''s always been a little "individualistic," so to speak, but prompt at responding. Maybe he''s ill or his mail is backed-up. I always phone him but don''t have his new Texas number.
Have you tried Hodgkinson here? http://www.scotgem.demon.co.uk/ahodgkinson2.html
