I bought the only three commercially available box sets of 'Naked City' whilst on holiday in America and I'm sorry to say that the episode 'Pedigree Sheet' is not on any of them. However I can tell you that the complete series of 'Naked City' is available from an American website called iOffer.com for around $56(£30) plus shipping. Apparently the viewing quality ranges from 7-9 out of 10 depending on the episode. If you are intent on acquiring the episode in question then ,to my knowledge, this is the only source. I would advise that you be extremely cautious and check out this seller first before parting with any cash. Good luck with your search.
