the closest thing to what I think you want to do (overlay the old maps
over new cartographic material). I don't see this happening in OSM though.
What I remembered was
http://www.npemap.org.uk/
where old British NPE maps have been scanned and stitched together
in a zoomable web interface. In my dreams, this was based on
OpenLayers, but in reality this website turns out to be a more
primitive solution.
But perhaps I'm not so mistaken after all. From the article
http://en.wikipedia.org/wiki/Leeds
if I click the coordinate in the upper left, I arrive at
http://toolserver.org/~geohack/geohack.php?pagename=Leeds¶ms=53_47_…
where one of the alternatives is "Ordnance Survey NPE 1:50000
(England / Wales), 1945-1955 (via OpenStreetMap)",

OOC stands for out-of-copyright maps, so this is where I should go.
Maybe this only concerns OSM and not WMF at all? I think WMF with
all its cooperations with libraries and other cultural institutions
could help to liberate more old maps for OpenStreetMap.
