I have posted on my website details of where to obtain cloned Cox plugs and in response to a query from Atlanta Georgia (Thermal Thumbers) I am placing the details here for thoses who are interested.
We have cloned the 1702 Hi compression glow head and have sold hundreds with no complaints. I do not recommend using higher than 40% nitro with this glow head.
Glow heads CAN$4.00 each + S&H.
They can be ordered from;
Langley, B.C. V1M 3A8
There is an email address, and to circumvent “spambots”, you will have to rewrite.
