Woodsmith/ShopNotes did a plan for a rebuild of the No. 888 (a slightly larger
version of the 801) in a recent article and offers the plans here: http://www.woodsmithplans.com/plan/antique-
toolbox/">http://www.woodsmithplans.com/plan/antique-toolbox/

The plans are in ShopNotes Vol. 23 Issue 134.

They got around the sourcing of the hinges by using regular butt hinges.

I own an original No. 888, and in looking at it I don't really see any advantage
to the modified external mount strap hinges.  The sides and top are 1/2 inch
stock and surface screwing into it would offer marginal strength increases over
normal butt install in my opinion.

I am also in the process of making one of these and am planning on dovetailing
the sides (why? Because it is cooler) and will use the butt hinges (why? Because
it is a lot easier and it will be a user tool, and there are so many other
details like the other hardware, plaques and decals that are not sourceable)
