Vintage LM Cox Tee Dee .010 Gold "Tie Clip with plenty of zip".  Supposedly only 100 of these were made.  Looks like new.  Paper it attaches to is ripped.  Literature has been folded for many years, but is in good condition.

See pictures and check other listings for more similar items (engines, coils, pressure tanks) that are currently running as a 7 day auction.

Unused shipping funds will be returned.  I'm just getting back into ebay after 2.5 years off.
