Here is a rarely listed full set of Cochrane bells. These are a nice purple -- The top cap is marked with the patent and the hardware all looks very nice! I did not disassemble the set, but the bells appear in great shape with maybe a peck or two (VNM or better) -- $2500 plus actual postage.

NOTE: I'm selling these insulators on behalf of the Jim Fielding estate -- PayPal (no fee friends and family) or checks are both accepted - I'll provide instructions. I'll also be handling all the packing and mailing.
