The Adventures of Hiram Holliday

I also remember somewhat vaguely "The adventures of Hiram Holiday", they were excellent for their time and really wonder if they would stand up to the test of present time. Memory is a funny thing, something like this is generally best left as a hazy memory than revisiting them and being extremely disappointed. In this case I feel confident I am not wrong and would very much like to locate a copy on video or if possible on DVD. I don't know if there are any archives of this programme /series available to down load or purchase or to which direction I could be pointed so as to revisit this childhood film / TV memory. I seem to remember Hiram Holiday always had an umbrella with him, which on more than one occasion managed to help him out of some dangerous situation. I look forward to hearing from any others who can help revive these memories. Mark
