‘Doctor Who’ thing of the day: build your own Dalek

Letters of Note -- an awesome site that publishes cool old documents and letters -- recently unearthed a most intriguing Doctor Who artifact:

From the production offices of the BBC in the early-1980's, we have a rather cute, and for some reason - to me at least - highly amusing letter informing an avid Doctor Who fan named Ronald that his request for Dalek blueprints had been successful. It's also a form letter, meaning the BBC must have been inundated with requests of a similar nature since the blueprints were initially released to the public, in 1973.
