See above... AW not 1910... so yeah probably easier to change a cog to get what I want to build, rather than change everything else just to keep Henry and James happy... I believe, since I have taken a couple of these apart now multiple times, that to keep the vintage rattyness of the bike I am building, putting a skiptooth cog on an AW hub (which I have and have parts for...) allows me to continue to use the nice skippy crankset and chain that is currently on the bike. Besides, I actually like to raise the eyebrows of all the cork sniffers...Sturmey-Acher was running 1/2"-pitch gear from jump. Here's a picture of a 1910 model, which has the 1/2" sprocketYou'd probably have the easiest time running an Ichi cog. Or, of course, running 1/2" chain, like Henry Sturmey and James Archer intended.
Just trying to confirm that, indeed, there weren't skiptooth Sturmey-Archers... not even earlier models had'm, let alone the comparatively modern AW.
