Sputnik Detail needed

I am making a model of Sputnik ! yes that's how crazy I have become

Does anyone have any images which show detail if there was any on the ball of the space craft ? I have looked at some online and in books but there seems to be very little detail in the images. Perhaps it was a smooth sphere ?

Thanks

Deirdre,

I found this
and this

I think they are replicas but the nasa page should be accurate.

Michael.

Thanks Michael the second image has a double ridge and some round things on the bottom so that should be fun
