Prop Hub Lock Nut

I haven't sold my 24 but did have the opportunity to expend the fleet....with a Fleet 16b biplane. I belong to the Fleet discussion group on Yahoo and have already posted there.  However, I am in need of a very specific part and hope you all won't mind my posting here as well.  Thanks.
The Fleet has a Kinner B5 engine of 125h.p. With a tapered crankshaft. After the prop hub is put on the shaft a conical nut gets screwed on the crank to secure the hub in place on the shaft.  As a final step a larger lock nut goes over the conical nut of the shaft and screws onto threads on the hub itself thus locking the conical nut in place.  The whole thing then gets safetied so as to prevent it from backing off. 
I would appreciate it if any fellow Fairchild Club members who may also have Kinner parts could please check to see if they might have the large lock nut that I have described. I really need one and just thought there might be a chance that someone here has one they can spare.  If so please post here or drop me a note or feel free to call my cell phone anytime.  Thanks very much.
