Hi All,
Thanks for all the feedback. One important note is that the downward protruding tang is not at the very front of the dropout as illustrated the jpeg Randy sent. The tang hangs from the front of the lower edge which the axle rests on; in other words, just like the the derailleur side DO hanger except smaller and without the very bottom round part that the derailleur would mount onto. So far, Russ Fitzgerald's suggested use makes the most sense to me. I'll try and borrow a camera. Russ F. and David G. any chance of posting a pic from one of your bikes on the PX-10 website?
Thanks,

Troy, et al-- If the 'tooth" you are referring to is the one shown on the "C. B. Continental" dropout as shown in the Claud Butler brochure, This is quite similar to the "Stallard" dropout that is on my '48 Rensch and Waller-- I was told that it's main function was to keep the axle from moving forward and fouling up the osgear shifting mechanism mounted on the chain stay. Having them on both sides would certainly enable insertion of the wheel into the dropout. One set of mine has a round area at the top of the "tooth" that would lock the axle in a fixed position, or you could slide it back into the dropout conventionally.. HILARY-- please help me on this one! With regard to something like that being on a PX-10, I havn't the foggiest. I will add a jpg photo of several types of dropouts availiable in the late 40's.

Hi Eric,
I believe the "tooth" is meant to help locate the dropout as well. Check out the CR link listed below. It explains and shows the Claud Butler version of the tooth and is quite large.
