On a whim I picked up a Gibson Les paul today and the Neck felt familiar.  Fenders are my go to weapon for audio carnage, so I'm still pretty new to Gibsons and their ilk.  I realized the the last neck that had this shape and feel was the Mosrite 350 and the one encounter I had with Chris Flanagan's (the Volcano's) Ventures model he let my try out.  But, maybe a little thicker than a Mosrite.  I read that Semie Moseley was a former apprentice at Rickenbacker, but I have no idea what their necks feel like. 
So, guys would you say this is a fair assessment?  Do Mosrite necks feel similar to Gibsons (circa 1960)?  Or am I way off base?  They feel like a slim "U" shape to me.  I need to shape to back of my neck and dont know where to start profiling.  I don't want it to end up feeling weird.  The neck is already pretty thin, and dont want to take off much more meat off the neck.
Also,
 if there is a guide to shaping Mosrite necks, I would be glad to find it.
Thanks everyone for their input.
