Gents I'm finishing an Outlaw ARF with a Webra 32 & MCP exhaust.

It's a used low-time motor. I pulled the plug to identify it (thinking I'd get a couple spares) and it's like nothing I'd seen before: long threads with an idle bar. I see no writing on the plug to identfy it. Filament looks good.

So I'd like to get a couple spares. I did a search "Webra and 32 and plug" and did see what I wanted.

Any ideas? If possible, an "ordinary/avail at LHS" plus (ie, OS) would be more convenient than some of the rarer makes (K&B, Rossi, Fox, etc etc).

Thx for the help!!
