12" bicycle wheel hub dimensions?

[derei]

Hy,

I am working on a project and I need to draw a 12" bicycle wheel (complete) and the hub is a part that needs to be fairly accurate (spindle diameter, fitting distance, etc).
I was able to find some drawings with dimensions, but only for some indian standards, which I am not sure how universal they are.
I don't even know if 12" wheels have different hubs from the 16"/24" wheels that are most common.

If anyone has some data regarding this, would be really appreciated. I am looking for wheel with spokes, not plastic wheels.

Thanks.

search Sheldon Brown 12" wheels, may not be much there, but he was the first person in the world to start uploading bike stuff on the internet...

I'll measure one a little later on...

my guess is 90mm...

Sadly, he died a couple of years ago,

I did fly to Boston one weekend just to meet him, and have a chat before he fell ill...
