              It looks like a ETA diesel. I'm not a diesel aficionado however. Ken

Ken is right. It is an ETA, 60's vintage and they were nice runners

Yes it's an ETA 15 diesel, albeit with non standard venturi (the banjo is missingas well) and spinner nut assembly. Still should bring a good price on ebay if the rest of it is in good condition. Mostly good motors, and were used successfully in FAI Team Race before the Super Tigre 15D came along.

Made by the great Ken Bedford in the UK. "ETA" is a alphabetical Greek symbol used in Physics, the symbol is embossed on the front of the crankcase.

Here's what it originally looked like

It is interesting that Ken would name it after Greek symbology. I was curious as to what may have prompted him to call it an "ETA".

Closest I could find that might possibly be a reason is ETA is used for example for one ideal engine cycle, Carnot Cycle efficiency.

It's been a long time since I studied thermodynamics and now it is all Greek to me.  ;D

This brings up good memories of my friend Don Myers who campaigned an ETA in his FAI team racer the Quasar. Beautiful silver model with elliptical wing. Wonderful time for team race before big money and high speeds ruined the event.

" Trade Mark" in the lower part "Watford England"

Great ETA pics and technical engine drawings there too.

Cheers.

You have enemies? Good. That means you've stood up for something, sometime in your life.
 Nothing in life is so exhilarating as to be shot at without result.  It's not enough that we do our best; sometimes we have to do what's required

Chris,

that's a good link. I have a few ETA .29's from MK 3's to MK 6c's. Two are in Vintage  B Class Team Racers. Our US friends may be interested to know that the glow .29's started out as McCoy .29 inspired near clones but eventually surpassed the original.  Stopped production about 1968, although they were available for a few years after that.
