I am surprisingly often asked at work what particular machine would fit the date / location etc of the current film or scene in the film.  Set decorators like to get things right in this regard, and delving into a completely new field of study (typewriters) is impractical given the limited time available.

So I'm wondering if anyone knows of a site that can be used to answer this question; ideally, you could scroll to the required date and see a picture of all the machines from the popular manufacturers which were current at that date.  Obviously, machines from previous years would also be a possibility.

I suppose it's a bit of a long shot, but I learned long ago the value of briefly stating the obvious at the beginning of a meeting, and that the only stupid questions are the ones you don't ask - right?
