Does anyone have or know where I can find a top down view of the Series 7B roof/lamp clear enough that I can just about see the scale of the lamp compared to the bit of the roof it sits on?

I haven't seen any of those photos or screen grabs yet, but the roof (top stack of it) is 43 9/16" (or 110.57 mm) wide, and should be square. (Granted, this is for the 2010 Series 5 TARDIS, but it should be pretty close to the Series 7b version. I thought I found a PDF with those measurements in the http://tardisbuilders.com/index.php?board=77.0 section, but I've been looking and can't find them now. Any thoughts from you, Bill? I know you've done the 2005 version, and have a good eye for the different models, so how's that PDF's accuracy?)

So, that's for the top roof stack. The lamp cap measures 7 3/8" (190 mm) in diameter at its widest. (I just measured my Gardman Lantern cap so I can vouch for the Imperial measure, but my stanky old wizzard(sic) eyes don't have the resolution to get any better than what I can see on the metric side of my ruler; but just to cover everything and try to be as accurate as possible, I put this through my computer's calculator and she says the metric is 187.325 mm... let's call that 187.33 - not bad: less than 3 mm off, for having stanky old wizzard eyes, eh?)

Anyway, I hope some of this is helpful.

Dino.
