That was from a reconditioning specialist, he said he could replicate something similar for about £350 and that was about 10 years ago .
The ends are cast iron and have special heavy duty bearings I believe.

Re: Works Dynamo
It's even got the massive weld in the correct place, just needs the tacho drive blanking and painting black.

Re: Works Dynamo
Hi Nick
See the AEG305 Head thread. Another picture of the dynamo with the big weld on it and the end plate as per works. On a Sebring Sprite.
Have you determined the diameter of these dynamo with the large weld?
Again, it looks wider in the Sprite photo.

Re: Works Dynamo
They are 4" same as a standard C40 the ones Jim builds use a C39 case which is also 4" . It must be an illusion on some of the old images, unless they are using the C45 case
