Found original part?

FWIW: I added a wiki page for the slide projector http://www.rebeldroids.net/wiki/index.ph...=Paterson_"Trident"_Slide_Projector - with links from the Treadwell Wiki page http://www.rebeldroids.net/wiki/index.ph...nstruction

The link to the new page that you put on the Treadwell wiki entry is fine, but the first link in your post here is broken.  The forum software is getting confused and thinking that the first quotation mark is the end of the url.

The "insert a link" button on the toolbar in full edit mode escapes the quotation marks properly: http://www.rebeldroids.net/wiki/index.ph..._Projector
