Found this in my junk box.
1 3/4 diameter, marked J.G. Standard, Nr. 1346.
Works great - are they still available?
I had the same thing in plastic but the ground was harder.

I'm guessing the plastic one was lighter. Is that steel?
-
Hi, MM - no, it's aluminum.

I had one of those. It was/is about twice the weight of a Froom or Brodak.
Cheers, Jerry
PS: If you need nose weight, they are great!

Up through the early '70s, the Williams Brothers plastic spinners were made that way. With the increase in popularity of electric starters, they changed over to the ones that used two screws to hold the front cone in place. Could J.G. be "Johannes Graupner?

Back in the '50s and '60s, the British firm KeilKraft offered a whole range of plastic spinners of that design - I've still got some of them in 1/4" steps from 1 1/4" to 2", and they were all right(ish) for small engines up to 3.5cc. They were popular because they were cheap, and the only trouble was that the screw-on nose cone sometimes flew off when the engine cut - especially annoying if you were flying over grass!

Spinners of that alloy type were also made by O.S engines in the 50s to maybe early 1960s. They were horrible things which relied on the front face of the prop being perfectly flat and square to the shaft to avoid vibration. Best use these days is to leave it on the bench to use as small paperweight.

Incidently the U S one there & the Kiel kraft noses are interchangeable . Saw one on Gogle pitchers years back , new in the box .
Yes , you need to see that the rear face is flat where it abuts the propellor , and that the prop cut outs are sufficent .
