More mid-range time frame "To-Do"s:

Add new chapter to "...Prototypes" Article regarding "The 10"

Create Articles on:
   Search for and ID of origins of Crich Box
   Box/Post numbers over time - deductions and corrections as to how many, when and where, and of what type (soooo many errors)
   Non-Trench type Met Boxes/Posts "When is a Police Box not a Police Box?"
   Box/Post signaling systems used over time, with electrical/wiring diagrams, details and explanations, etc
   Updated scans and discussion of origins/provenance of Trench Plans
   Locks and Keys, including keying guides for:
       Met and other city's Box keys (where available)
       TARDIS locks and keys over time (Yale type)
   Police Box and Met Box Mythbusting -- Common (and uncommon) myths and misconceptions; setting the record straight -
        Including the following myths:
          There were only 3 types of Met Box
          The difference between Marks 1 & 2 were just the signage
          All Met Boxes were concrete except for a few "mock-ups" or experimental examples
          The Trench plans were the original 1929 blueprints, proving the above
          Mark 1's didn't originally have top lights or handles when commissioned
          Mark 1's had lead sheathed roofs
          Mark 1's were made entirely of wood
          Mark 1's were made entirely of concrete
          Mark 0's were just decommissioned Railway watch boxes purchased by, or given to the Met
          Non-Box or Non-Post communication points weren't numbered
          Met Boxes being used as mini-jails until transport could arrive was either a myth or an afterthought
          The Dinky toy was wrong, Met Boxes never had red top lights
          Met Boxes had blue lights at one point
          The first Police Box that looked like a TARDIS was installed in Newcastle
          The Cushing Box is a close copy of a Met Box
          Etc.
   Series of "Origins" Articles about the precedents to the later Met System and its Boxes/Posts, including (but not limited to):
       Met Fixed Points 1870 and 1877
       Chicago 1880
       Glasgow 1891
       Early Met Police Telephone Boxes (Mark 0s) 1897
       Crawley's System (Sunderland, then Newcastle and beyond) 1923
       
Create at least rough draft CAD drawings of all Met Box Mark types to:
   Create "Usual Suspects" chart
   Create "Spotters Guide" (mostly details of roof lines and window patterns in addition to "Usual Suspects", with annotations)
   Create Article on differences in form and construction over time


Not directly tied to the Metbox Catalog, but at least loosely related (as will be seen in some cases):
   Create Topics or update existing Topics with findings for:
       High Wycombe
       Hastings (but also re-research and document alternative theory for Hastings connection)
       Dover
   Update Glasgow Database and Catalog with all findings (lots, and lots) as per Met section
   Coordinate with Starcross on Articles for each Glasgow Box Mark type
   Create at least rough draft CAD drawings of all Glasgow Box Mark types (with similar reasons/goals as with Met Box CAD drawings above)


And finally, on a more personal note, create Topic on building and history of the TARDIS Assembers Union/Gallifrey One TARDIS with what photos I can ferret out of storage.
