Deletion of Pentax MV 1

Comment: Wikipedia does not attempt to provide an article to describe every Pentax camera model. There is no policy or guideline to suggest this. Have a look at "Pentax Optio". In any case, "|What about X?" is not a suitable argument at AFD. The Butkus website contains only the camera's manual as a pdf. It does not establish notability. I have struggled to find reliable sources to establish notability. I have added two references. McBroom's book is a reliable source. However it does little more than mention the MV 1 in passing. Classic Cameras & Photography is a blog review, thus has questionable reliability. If better references can be found, this article could be worthy of inclusion in Wikipedia
