Unknown head adapter

Re: Unknown head adapter
It says standard plug, but it looks like a turbo head.
I'm guessing late 70's, since the application cites
TeeDees and QRCs, the only TeeDee head equipped
Cox engines at the time. Doesn't that pre-date the
turbo head?

Re: Unknown head adapter
I haven't seen that specific head before but there were several companies that made a little "shroud" or compartment around the end of the regular plugs. This was supposed to help with the power loss that regular plugs had on smaller engines. Norvel/Steels had heads like that for instance, see figures below.
So from a distance it looks like it is for a Turbo plug with a regular thread diameter, but there is no cone at the lowest part and the end of the glow plug should not reach or touch that restriction.
