Not sure what you are asking.
But
The difference between a H&C and a CJ H&C will jump off the chip right at you.
The bottom of the hat on a Christy Jones H&C is very shinny. In fact some chippers call them Shinny H&C's.

Christy Jones went out of business in the middle 60's when Bill Christy and Bud Jones split up.

Bill Christy and Paul Indy (Paul-Son) had some alliance for awhile. Paul-Son wound up with a redesigned H&C. Not Shinny.
The LCL and RCV came along in the 90's, I believe. I think there is another one with a short cane. Greg can help with it as he named them. I think.
