Got some reliable Plans

Ok, Went to The British Museum over the weekend and accessed their archives.
I found plans from 1807 of the building, with a scale, on Microfilm.
Printed off some copies of 25 or so useful seeming pages. (There was over 150 pages...a surprising amount of which were basement images...)
Anywho, re-scanned the images onto a pc, but for some reason they exported from the scanner as a multi-image tif file... Got preoccupied with other things, and only just got around to converting them to jpegs. These are a few of them.
